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?

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.

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.

Hickok 600A

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.

The TV is a nice compact military version Hickok.
