I am not saying that you should not purchase a Hickok like a or at the are compact bench top models that are basically laid out as this A above. Use this procedure to test and calibrate the Hickok Model /A mutual conductance (AKA transconductance) tube testers. Except as noted, all of the. I have a Hickok Model A tube tester that I’m learning to use. Hopefully someone here can answer a question for me. On the micromho meter.
Data is widely available for the B, C units. It’s not like we’re doing life tests on ‘s. I say go for it!
The full military manual comes with instructions regarding hikcok destruction of the tester using explosives, axes, or throwing it overboard, to avoid the tester coming into the possession of an enemy power.
Hi all, Is it worth buying one of these, I’ve seen one and know how good they hickol, I’m getting more into tubes and it would be great to get one and fix it up, if possible. It is classic military construction with potted transformers, ceramic sockets on the minis and octal, and hermetically sealed caps. Nice little unit, and adapters are easy to make And if you can’t find “tube data” for a particular tube Also shop in Also shop in.
Do you already have an account? Haven’t found any official Hickok documentation on that, but there’s a fantastic thread here about it: About a zillion years ago I made an adapter from an old tube socket for mine so I could test ‘s.

Provide a checklist and instruct There is supplemental test data for TV-7 available online. Yes, my password is: Log in or Sign up.
If you don’t hifkok to test modern types like Novars and Compactrons,this is a great machine. The A does not have this. How hot do a pair of essentially unloaded rectifiers get? Upset that and you’ve upset the whole applecart. No button cover knobs are included. Fixer-Uppers will cost more to fix than buying a good one.
The TV-7 is very similar to TV but has flip-chart tube data in the upper lid of the unit. The biggest issue is that the power cord’s insulation is starting to crack in places, and also the plate cap adapter cable is brittle and cracking.
Sam CogleyDec 9, Hickok Hickok A Hickok A. Has sockets up hickoi 9-pin mini. Hi Tom, Are they easy to calibrate to be able to test some 600w
It is basically a A on steroids. If most of the screws are 600z it means that somebody knowledgeable looked inside and decided the tester was SHOT and there was no point in bothering to put all the screws back in.
Check neon bulbs and operation of short detection ihckok. I need to watch that A video just to make sure my A is calibrated properly. These are nice compact testers and data is widely available.
And I gave up checking the calibration years ago,as it has never varied from the very first time I checked it. Big HarryDec 8, That’s what the unit was designed around,with due consideration to filament draw and sag under different load conditions. I bought a large lot of 1 volt radio tubes from a radio amateur’s estate sale and am testing them and passing them along to you very cheap!
Tom BavisDec 7, It is used and in good shape with light wear. And as mentioned above, you can make an adapter if need be. I’m sure these tester are build to last, it should be fun digging into it and doing a restore.
I dumped it as soon as a I could afford became available. And you know what?
This is the best of the basic early testers. Sam Cogley and thorpej like this. They are older than the B and C’s, and for this reason it is important to only buy one in good working order, but this tester has been my bench tester for over a year, and I have gotten to like it a lot.
Plus,the heat is your friend,as it keeps the humidity at bay,and as there’s so many holes in that panel,there’s plenty of ventilation.
