Anybody have a good lead on where to purchase one? All I see are a bunch of vintage units not verified to work. What do you guys use or do to test efficiency of tubes?
https://maximatcher.com/ is THE tube tester but they are real expensive. If you want accuracy those are it though.Anybody have a good lead on where to purchase one? All I see are a bunch of vintage units not verified to work. What do you guys use or do to test efficiency of tubes?
I saw this too and it looks like they’re the only ones I can find.https://maximatcher.com/ is THE tube tester but they are real expensive. If you want accuracy those are it though.

This is exactly what I did a few yrs back. Use the same amp to test the milliamps in each tube....write that number on the tube base, and now you can match all the like numbers up for a good quad/pair.Maximatcher is the ultimate tube tester, but boy is it pricey. More than I wanted to spend anyway.
I kept an eye out and eventually got a verified working EMC 211. It works enough to check for shorts and tell if a tube still has life in it. For matching power tubes I'll use one of my amps and keep track of tube readings.
Maybe see how much it would be to have a vintage one serviced and take a chance on one of the unverified ones.
In the early 90's that was the go to dating website for lesbians. I guess the domain name had expired. Surprised 3rd power amps didn't register it.https://maximatcher.com/ is THE tube tester but they are real expensive. If you want accuracy those are it though.
So how do you test preamp tubes?Just use your amp; its the best tube tester you can have. It will tell no lies and test everything including how they SOUND. Just have a few fuses handy if a power tube is shorted.
Plus, you can match power tubes too if you can measure the bias current while testing.
I do this all the time with great results. No need to get an old tube tester unless you buy and sell tubes that you don't use in your own amps.
Yes, and no. The problem is if you put a bad power tube in, even with fuses a tube can still damage the OT. It's not supposed to, but I've read about this happening.Just use your amp; its the best tube tester you can have. It will tell no lies and test everything including how they SOUND.

I have a cheap mighty mite from probably the early 60s. Works great; tests for emissions/leaks/shorts/strength. 50 bucks on ebay 10 yrs ago.
Never let me down.
I use V1. I just swap them in and check for microphonics, if they produce sound & if it sounds good. I have a plexi so I can test both sides of a 12ax7 with each channel.So how do you test preamp tubes?
I agree with the power tubes. It can be a little risky.Yes, and no. The problem is if you put a bad power tube in, even with fuses a tube can still damage the OT. It's not supposed to, but I've read about this happening.
My cheap 1960s tube tester serves the purpose of checking for bad tubes, so I don't install one and risk anything. I also have checked all my power tubes in the same amps and measured them; a great way to then match up a pair or quad.
