Theoretically I'm only interested in gear from the 1970s to early 1990s, that 'could be useful' for my assorted development projects. I rationalize this preference with the argument that during that period these manufacturers were run by engineers not lawyers, and so they produced excellent detailed operating and service manuals for their instruments.
http://emadjoe.com/images/brother-embroidery-machine-manual.pdf
These included full schematics, theory of operation, diagnostic and calibration proceedures. You see engineers naturally understand that the owner of a piece of expensive test gear has a right to expect availability of everything necessary to maintain the equipment themselves. Whereas a 'suit' will immediately start calculating how much more profit they can make by forcing customers to rely on the manufacturer for all equipment servicing. Therefore, why should they make the service manuals publicly available. Besides, it's all proprietary information, and must be kept secret so their competitors can't just copy the products, right. Even better if they can build in deliberate operating restrictions and lifetime limits, requiring customers to pay for 'upgrades' and then buy a new one at some predictable time in the future.But that's a sidetrack I won't pursue here.Since, no service manuals available. Not to mention that it's too expensive in the first place.So I cut my ebay buying habit right back, effectively to zero for larger units.Then I looked at the seller's other items.And he's in Melbourne, Australia, so shipping would be cheap, plus there'd be much less chance of the instrument being damaged. It's a sad truth that maybe 20 of all my purchases from the USA got damaged in some way during shipping. Sometimes seriously.Plus the instrument's design style is so unusual (for Hewlett Packard.) It's a very pretty piece of gear, and something I definitely want.Yes, I saw the tilted power switch button.I have a few pieces of GRC gear, and it's always beautifully engineered. Plus, this is useful as an accessory for the Q-meter.The ebay seller has almost no prior history. There's no way to get any idea of how reliable they are. This is a big worry when considering buying several hundred dollars worth of stuff from them.That Q-meter is worth it. And I might as well bid on a few other of his items as well. It's a long time since I bought myself something nice.
I end up with this list, for bidsniping setup. In the order of auction endings:GR precision variable capacitor. HP 34401A 4-wire multmeter. An insulation tester. HP 4342A Q-meter. Bird RF Power analyst. An old Grid Dip meter. A 128A Lock-in Amplifier. An old Leader oscilloscope (as a gift for a friend) With over 30 hours till these items start to end, there should be no problem reactivating my account for a minimum interval. So I log in, and pay the small fee for a one month activation. The site claims activation should happen 'instantly'. Of course it doesn't happen instantly, or even in the next hour, so reading the fine print elsewhere it turns out to specify 'within 4 hours.'Six hours later, still nothing. I send a message to customer support asking what's up, and go to bed.They seem to be ignoring both the payment and any queries I send, via any of the possible methods. I give up on them, start looking for alternate bid sniping services.I recall that ebay bought up bidsniper.auctionstealer.com, so perhaps that one has become a walking undead zombie too, just like ebay. Anyway, one called seems like a good deal, and they offer a free trial use. Enough for my purposes here, so I sign up.I set up my list of auction numbers and bid limits. Fingers crossed that bidnapper actually works, when the 'last 5 seconds' comes.Yep, they've gone totally ebay-ish.Woke up, think 'hmm.Wait, the auctions!' Got set up to watch the process in plenty of time. This is when I discovered how neat bidnapper's bidding status page is. Really a very cool example of dynamic html. I'd placed bid limits on the probably high priced LCZ and HP multimeter that would only win if the competition wasn't too great, and they went for relatively low prices. Because I don't really need these things. On the other hand by now I've developed a severe case of 'HP Q-meter want', so I decide that I'll transfer bid weights across to the Q-meter from other losing bids.

Since, that total was what I was prepared to spend anyway.Also the Lock-in Amplifier, cheaply enough to justify on the grounds that I'm curious to play with it, though it might be a devil to find a manual for. I'd already found and downloaded a manual for the Q-meter, however getting a physical original is now on my to do list. Fold-out schematics just don't work with pdf documents.Just more than I wanted to spend. I send an ebay question asking what shipment options he has. Also, since I might be going to Melbourne around 7th March, if there's any chance of waiting till then to pick it up in person. And one more thing - since he'd said the items were being sold to make space due to a move, did that mean they were previously in use and in that case, did he still have the manuals for them. Would he sell them?But did reply well to later ones next Monday. In that first one I'd mentioned that I was worried about the fragile banana posts sticking up from the top of the Q-meter, and asking if he could be sure to pack it so they didn't get broken during the parcel tossing that always happens during transport. I felt a bit guilty about even mentioning this, since it's such an obvious matter. I didn't mention it again. I wish I had.Cool! The TNT courier had one of those electronic data entry things, which you're supposed to 'sign' on a touchscreen with a stylus. I have no idea how anyone thinks those things in any way capture acceptable signatures. They just simply don't. You sign, the result is a series of jaggy lines due to a way-too-slow sample rate. Well whatever, just another small example of mass technological delusion, no point worrying about it.This is always the best moment - except when it isn't.Opening it (from the top), the thin rack mountable Lock-in Amp is on top, among an assortment of styro chips, foam blocks and bubble-pack. Very much re-used packing materials, but that's no problem as long as common sense is used. I remove the Lock-in Amp, and.
It's been put in upside down for some reason. Ok. The GR variable cap is off to the side, wrapped in a couple of layers of bubble wrap. I pull it out; it seems like it's OK. That leaves just the Q-meter, among the mixed packing materials. I hope it's OK like the others.With a neat pattern of crush marks that obviously match the arrangement of the banana posts on top of the Q-meter. Twice.Surely there'd have been some blocks of foam or something.So it was effectively resting most of its weight on the banana posts. Plus the weight of the Lock-in Amp.It looks like the posts are all intact. Oh. but wait, is that one bent? Sigh. Yes, it is bent. Not a lot, just enough that it's too much to ignore. And I know the structure of those. Thin threaded brass tube, that will be virtually impossible to straighten without it breaking.It's not a standard banana post, it's a special gold-plated, custom machined unit just for this instrument. It later turns out that even the individual posts on the Q-meter are different. The bent one has only one the same. Not that this helps.The damage is small, but completely unacceptable, and will be extremely hard to repair. The very best option would be to just find another whole but not-working unit, and use it for spares. But chances of finding another in Australia are approximately zero point zero. And shipping from the US would be at least a hundred dollars, more likely two hundred. Meanwhile, the damage is entirely due to completely imbecilic packing. The person that did this was a total moron. It's not the worst case of stupid packing I've ever encountered, but it's pretty bad. (The worst was a US seller who placed a Tektronix 7000-series rackmount scope in a considerably larger box, and sent it to Australia with absolutely no other packing materials inside. Result - badly trashed scope.)So now, here is a tear-down of a HP 4342A Q-meter. I did power it up first, and it seems to respond sensibly to controls.
But finding out if it works correctly and in-tolerance is going to require some reading of the manual, so can wait. Besides, since I have to take it apart, better to only do the cal-checks once, afterwards. By then I should have a paper (ie conveniently readable) manual.I was in a rush.) The Line button cap is broken, but repairable. I'd noticed it was crooked in the original listing.While moving it around I had noticed the sound of something small rattling around inside. No sign of it yet. It's a bit sad that HP skimped on the thickness of the gold plating, so now it's more like tarnished brass.Not a single IC in sight. The two TO3 transistors are venerable 2N3055.Switching is done via mechanical linkages from the front panel, and the vane capacitor is mechanically linked to the left hand roller knob. All adjustment links are zero-play, and feel really nice to the touch.There's more mechanics in this thing than electronics. It's rather nice to look at, but I wouldn't want to have to disassemble this stuff and then get it back together with the indicator dials still in calibration. Fingers crossed it isn't necessary.Much to my relief the solid plate has not been bent by the shipping impacts. So the only damage so far is the bent post mount sitting on the post-it notes. (I later discovered one of the outer 'shield' posts is also slightly bent.) The fine finger springs on the part at right contact each of the individual vanes of the adjustable capacitor underneath the fixture.Even blurry you can see how bent it is.It's looking like HP designed the thin upper screw section of the mounting posts as a kind of damage-limiting failure point. Under impact the posts would break off, while the internals of the machine should survive.I'd machined down the end of the metal rod to a good fit in the hole in the end of the post. So the rod is axial with the end part of the post. That's how bent the post is.
www.dubaimotorcycletours.com/uploaded_images/files/car-service-repair-manuals-free-download.pdf
I knew if I just tried bending the post back it would definitely break, as it's brass and the walls at the base of the bent part are very thin. The plan at this point is to try applying light 45 degree tangential blows to the end of the rod, so the brass walls of the post are nowhere subjected to tension, only compression. The aim is to re-compress the side that got stretched, while not tensioning the other side (because it would fracture.) Nice plan. Didn't work.The post was almost straight, although the tapping pressure was also slightly compressing the post end, making the threads a little under-pitch, so the knurled cap is a noticably tighter fit. Then right at the last moment, the 'pushing' suddenly got a lot easier. It was straight (see 'after' video), but.So it's holding together for now, but will break off completely at some time as the post terminal is screwed and unscrewed.It was a small screw, and for a while I was looking for where it could have come loose from. Nothing. and it's a steel, chrome plated M3 screw, while all fasteners in the Q-meter are stainless UNF. It so much doesn't match that I'm certain it must have been accidentally dropped into the machine some time when the cover was off. Since there's no ventilation holes, there's no other way it could have got in there. Mysterious.It's simple, it works, and the buttons have an interesting long travel and solid 'clunk' feel when pressed.Looks good, except it's fractured half way through.Should be able to do this, though I don't trust my minimal lathe thread cutting ability, so that's two thread dies I'll need to buy. If they were metric I'd already have them. But nooooo. They are American UNF threads.But here I am needing to source a unique mechanical part instead.Here's the whole exchange. Anyway, to cheer myself up I had a look inside the GR Type 1422-D precision variable capacitor.No bent banana posts here. I wonder what it was.
The chief function of the large clear plastic disk appears to be decorative, though it also contributes inertia when spinning the dial. Maybe that's the purpose. Anyway, it's pretty.One ten times the value of the smaller. Large one on the right here. Both have a 'profile adjustment' via multiple screws that warp small segments on one of the vanes. This is very much 'don't touch' territory.After calibrating the LCR meter zero with its leads in exactly that position but not connected to the GR unit, then connecting them, they agree perfectly.

PM please for offer. I have been measuring Q with the ring-down method but it is not accurate with basic scope and function generator. At the moment I can only predict unload Q with software. SingHowever, I would recommend you look for an Advance T2 Q-meter. I have one here and is a useful piece of test equipment. The lowest freq. that it will resonate a coil to is 100 kHz. If you do acquire one, you will need the manual: it's available on the www. Marconi made a Q-meter. I've never used one, but I have read reports that it a bit tricky to use. (And, I might add, in my experience, as an item from Marconi, that is what I would expect). Al.I don't see them around often.But the whole design of it, the mathematical support, operating instructions, the construction article and details are just wonderful. If you want the whole article, all you have to do is email Silicon Chip (they have this archived) and they will send you the entire article.I can always rely on design rule of thumb and approx.This was generally for filters across all bands from Someone in another forum had suggested me to download the manual and look at the method used in HP4342 instructions of measuring the stray capacitance of an inductor. But the method had turned out to not useful. But I must say the HP4342 manual has one or two interesting graphs and I was intrigued by them.Several years later, I bought a second-hand one. Briefly stated, it was almost useless. So I suggest that if you do see one offered, walk away! Al.But the method had turned out to not useful.
But I must say the HP4342 manual has one or two interesting graphs and I was intrigued by them.They seem very focussed on predicting 'where' the resonances will occur and then producing an equivalent 'capacitance' to produce this resonance. Or at least that was what I concluded the last time I read their stuff. I think David Knight has been doing research work into this stuff for many years. My experience of advanced inductor modelling dates back to the early 1990s at my place of work. We have to model inductors out to frequencies several times higher than the first resonance mode because we do a lot of ultra wide bandwidth design. Our goal was to produce real working (complex transmission line based) models rather than to try and produce equations to predict where resonances occur.Someone on here may have one for sale. If it's an HP4342A I'll out bid you for it (just kidding )The maths of the VHF stuff boggles my mind. It also seems that the owners of the HP4342 (guys from another forum) do not normally understand the logic of the testing steps outlined in the manual. Last week I was trying to figure out why certain test have to be done in specific steps and the HP4342 manual does not really explain the rational behind those testing procedures. Other less known Q meters would require lots of skills to restore and maybe it would be difficult to use correctly without the user manuals.Most of the RF stuff I do these days is SMD but in the 1990s I did make a lot of coils for filters across LF through VHF and these were fairly large coils with lots of turns. I often used Litz wire for the LF stuff with various RM cores from Siemens to achieve a Qu up in the 400-500 range. That's when the decent Q meters leave the cheap and basic Q meters behind. It's also why I prefer to use other means to measure Q these days because I feel more confident in the results.
But for simple and typical MW coils that have moderate Qu I think you would be OK with a fairly old and basic Q meter. I can't comment on your Tesla coil requirements though!When time permits I'll be building this project. Regards SymonIt is simple to use and is fitted with calibrated variable C and goes from 50KHz to 100MHz. It will allow Q and delta q measurements, as well as dynamic R and self cap of the test coil. It has a small platform that allows accurate measurements. A rats nest of wires will not give accurate Q figures. Parts to replace are black hunts caps that are not in the measuring circuit and valves (2) are easy to obtain types. Used to be quite common on ebay but not seen one for a while. Use with a Tesla coil would only be at very low power as the coil would only be energised form the meter. EdMost of the RF stuff I do these days is SMD but in the 1990s I did make a lot of coils for filters across LF through VHF and these were fairly large coils with lots of turns. I can't comment on your Tesla coil requirements though! My high-power tesla coil scares the living hell out of me. It was a health and safety hazard. I had to wear gas mask and ear muffs during operation. It is important to predict the Q and coupling coefficient k before building a tesla coil. This can be done with a very accurate free online software called Javatc. The measurement of Q for tesla coils can be done in the same way as radio RF coils. Just out of historical interest in vintage technology, I made a few spiderweb RF coils with 100 threads Litz wire, I think the Qu of spiderweb coils can go over the maximum limit of some Q meters; probably Qu reaches over 400. In that case software prediction or measurement methods using scope and signal generator are the only way forward. T2A looks beefy and solid.
The maximum Q for HP4342A is 300 (up to 1000 with certain supplemental inductor combo) The maximum Q for T2A is 400Last week I was trying to figure out why certain test have to be done in specific steps and the HP4342 manual does not really explain the rational behind those testing procedures. Other less known Q meters would require lots of skills to restore and maybe it would be difficult to use correctly without the user manuals. It was a replacement for an old Boonton 260 (I think the model number was) It could certainly do a better job on high Q coils than you could do with a VNA but even so, you could run into its limitations. I have a feeling it was one of the first products of HP's Japanese subsidiary with Yokogawa. Search the HP Journal, there is likely to be an article on it explaining all sorts of things, look also for HP applications notes. There was also a Boonton Rx meter and of course, General radio's RF bridge. But give me a 4342A any day DavidI would certainly contribute to it. I've measured Q in lots of ways over the years and I abandoned the old Q meters many years ago. We threw our Marconi TF1245 away some time around 2000-2005 as no one had used it in ages. Typical issues were to do with the cal house wanting to engrave a new capacitance dial (at immense cost) every other year or so and they also bleated every year about the detector diode (valve) failing their tests. They wanted to import the diode valve from the US at a crazy cost and they wouldn't guarantee the new diode would be any better than the old one. So every year we asked for a restricted calibration rather than spend money on it. That's why I would urge caution with this meter. If you find one it's probably had several sets of fingers in it to fix the usual failures and it will be unlikely to be in spec any more. However, I have fond memories of using it because it can be very rewarding seeing that Q needle climb just a little bit higher than it did with a previous coil design.
