That's a Preceptor. I have a working model K. The guy I got it from was planning to make knife handles out of the panel.

Well, I guess when it comes to tube testers I'm fairly "germ free". I have a hickok 533 for "01's" through early 60s tubes, and a Grief-Kit IT-17 for compactrons and nuvistors.

Well having 8 should be no issue.
I have one that has something like 40 sockets for quick check, It really does go fast and Eileen will use it to run through a box of tubes, Otherwise she gets bored with the other testers. But it is limited to mostly octals and mini tubes.
Still I think at least one has to go, Maybe two if I can bear it.

I use, although infrequently, two lowly emissions testers, a B-K 606 and a newly acquired from a garbage pile Conar 224.

"How many tube testers does one need?"

Just one more grasshopper, just one more. :-)

20 or more, I should count them one day.

Hickok 539B for audio tubes
Hickok 600a for audio and other tubes
and other tube testers for general testing...

Only 4 here at my place being married is the limiting factor.

1 Eico 667 repaired and will be sold most likely on eBay,
1 Hickok 539C Very nice that is sold as soon as I complete a project.
1 Hickok 539B Late series in average condition to be sold when the project is completed.
1 Hickok 539B Early series, which has a rather poor case and I will keep it primarily to check out questions that arise from the project. I converted the Bias and Power meters to digital, since the old square meters had failed as so many of them do.

Project is the development of 539B/C Test and Calibrate Procedures along with the hardware fixtures to perform it safely for both the Technician and the 539B/C's. It will be sold as a package starting within the next couple of months. Bill Eccher

Hello! I have 2 ones: the old German WE252 Neuberger (1942 year of prod., with some self-made adaptors for octals and newest tubes) - for fast testing tubes of all types, and the famous Russian L3-3 for
accurate and detailed tests of all tubes, it's also with some adaptors.
My wife doesn't allow me to have more tube testers .... :)

WBR, Nick.

Yes, but I'll make photos some later (with good quality!).


(And little off-top: Steve, many great thanks to you for your nice Supreme-instruments site! Where I did find manuals for "supreme model 561 combination generator" some time ago. I have got this device from my grand-dad, and I repaired it for use to re-aligning my old radios. Have good photos of 561 inside, can post them :D Because
I collecting not only old radios, but some interesting test-eqipment too!)

Well I have been thinning the herd. I am now down to RCA WT 100A, Westmore 501, Weston 686, Triplett 3444, Hickok 539C and about 20 other assorted military, Hickoks , etc. I like being able to test a tube under actual operating conditions.

I have 3:
Jackson 103
Jackson 648-1
RCA 156-D

I use the 103 most of the time. The RCA tests some older tubes that the Jacksons won't.

I use the 648 to compare tube sections. It isn't the best way to test tube sections, but it's what I have for now. I'd like to replace it with a Hickok some day.

I also have a Jackson 825 CRT tester. Does that count as a tube tester? :)

I use about 4. A Seco, Weston, Universal and Hickok. Steve: I have a Preceptor model J. It has only 3 port holes, and one is a neon. Yours must be the super-duper deluxe version. You must need sunglasses for safety!

Based on what happened after church service a few years ago, I think I must have enough tube testers. After the Sunday service, our preacher shook my hand and to make friendly chat, he asked me "How's the tube tester and radio tube hobby going?"...I thought for a moment, but my wife quickly declared "It's slightly better than a cocaine habit !"....after that I couldn't say anything.

Guys, to get your wives to understand, simply tell them that you need one of each color to complete the set. That they can understand.

Here's a pic of the tube testers I picked up at a hamfest last month -

I didn't see any mention of a Sencore MU-140 or MU-150. I really like the design of them (5kHz square wave gm test). I use my MU-140 that I recently bought as broken and have since fully restored and the TV-7U that I just gave $40.00 for and will soon go over. These two let me do a reasonable job of matching triodes and verifying supected problem tubes. I also have a Sencore Hybrider and a Precision that I will get around to calibrating and selling to someone who can use them. I see that they have a place in the shop but most of my troubleshooting is done in-circuit. The tube testers are more to confirm that I need to order that replacement tube that I never seem to have on hand. :wink:
