Gilbert Posted January 9, 2006 Share Posted January 9, 2006 I've aquired too many tubes and too much tube equipment not to own one. So I finally did it. Lucked out and found one not too far away. <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Witchita, KS. The unit appears to be in excellent condition, other than a couple of small nicks in the carrying case, it look brand new. I have'nt got a clue how to operate it, and I want to have it professionally calibrated, and in 100% working condition. My questions are; Who does this kind of stuff? Who would you recommend?

intotubes Posted January 9, 2006 Share Posted January 9, 2006 I think I would use it as is if it is in working condition. Does it have the manual? I have the same tester. I haven't worried about getting it calibrated. The cost of having this done would likely exceed the cost of the unit itself. Maybe finding a friend that's an electronics buff with nothing to do. Other than that I would for an older TV repair shop with an old tech still running it. Good luck. Quote Link to comment Share on other sites More sharing options...

Thanks INTO, and yes I have the manuals (on order), and even found some info on how to calibrate the unit. From what I've read, it really doesn't appear to be that difficult to calibrate, so I really don't think (out of ignorance) that it will cost that much. Also, even though the unit appears to be Like New Condition, it was manufactured in 1953, so I really get that feeling that some of the components arn't quite up to snuff. I will play with it when the manual arrives, but won't have faith in the tester until I can get her professionally calibrated, and compared against some other units. I'll also need to read up quite abit about tube construction,....tube testing procedures, .... and learn to interpret my readings. Based on what I've read, No 2 testers (identical or otherwise) will give the same readings. Way too many variables involved. Quote Link to comment Share on other sites More sharing options...
DRBILL Posted January 9, 2006 Share Posted January 9, 2006 Michael Marx at vacuumtubes.com makes a market in tube testers. He could probably direct you to the people who do his work. He will also have your manual which probably has calibration instructions I got my tester (B&K-700) from him. It came with calibration instructions that took about an hour and only required a volt/ohm meter and a few common resistors. I was amazed the first time I had mine apart. There is very little to them! DRBILL Quote Link to comment Share on other sites More sharing options...

I haven't looked at mine in quite some time. I know it was calibrated several years ago. It's good to know it's not that difficult to do.

JJkizak Posted January 9, 2006 Share Posted January 9, 2006 Tube testers, aaahhh yyeeesss, now I remember, the old ones, and even then they didn't work too good when they were new. JJK Quote Link to comment Share on other sites More sharing options...
DRBILL Posted January 9, 2006 Share Posted January 9, 2006 Yes. It had something to do with the nut that held the on-off switch. [] DRBILL Quote Link to comment Share on other sites More sharing options...

This place does calibration and repair. $75.00 for calibration, $120 if repair is needed. http://www.alltubetesters.com/pricing.html A couple people have mention having calibrations instructions. If you still have them, could I get a copy of them? I'd like to see what's involved. Quote Link to comment Share on other sites More sharing options...
Gilbert Posted January 9, 2006 Author Share Posted January 9, 2006 Scott, that's the second time I've been refered to that link you provided. Another good source that I was refered to is vintage radio forum. Thank you, I think I'll be sending it to Rodger Kennedy. Has he ever done any work for you?

Gilbert, I had my Hickok 752 checked out by Kara Chaffe aka www.tubewizard.com When she got too busy to do work on tube testers, she listed Rodger's website as a new source for tube tester service. I haven't used him but it sounds like he knows what he's doing. Quote Link to comment Share on other sites More sharing options...
thebes Posted January 10, 2006 Share Posted January 10, 2006 Here's a very good Hickok website. You might find what you are looking for there. They do have alignment procedures but not sure if it applies your model. http://www.0wned.org/~hstraub/testerdata.htm Quote Link to comment Share on other sites More sharing options...
