I use a cheap vintage tester, Superior TD65 purchased on eBay and it gives me what I need to know and works fine. I highly suggest anyone with tube gear get one. It doesn’t have to be a very expensive one, but one that will tell you if a tube is bad, weak, or not.
Anyone Here Ever Purchased A Tube Tester?
Once or twice a day a tube sputters for a brief second in my Audio Research Reference DAC. The Reference DAC is connected directly to my amplifier and it also serves as my preamp. Visually, all of the tubes look fine. Visually, I can’t tell which tube may be bad.
The tubes are: (4) 6H30, plus (1) 6550C and (1) 6H30 in power supply
Have any of you ever purchased a tube tester to test your tubes? If so, what tube tester are you using?
