Title: Tube Tester
Post by: Brap on January 26, 2017, 08:45:37 AM

Thinking about getting a tester.  Saw a Sencore TC-130 on the bay starting at $99.  Thoughts on testers and anyone have comments on this one. To be used for EL509, EL-34, KT's and various 12 au/ax/ ECC tubes.  Thanks.

If you buy used, does it need to be checked out and calibrated? Probably not just for good/nogood. They do make high volt DC, so a 50 year old tester should be checked out for PS caps and correct voltages.

Since you've already built Transcendent amps, I assume you know about their tube tester kit.

Some newer audio tubes were not common during production of vintage American tube testers so you need to know the settings to use when testing those. I found it difficult to find settings for 6H30. EL509 may fall into that category depending on the model tester.

Yes, thanks Richi -- forgot about that in the book, appreciate the reminder.

Looks like Transcendent tester no longer available.  :(
