need to purchase a calibrated , small signal tube tester-why so difficult?!
Tired of not being able to test my own tubes.
I know enough to not just blindly go to ebay and buy a vintage one….even if says “calibrated.” I’ve contacted some of the legacy folks/sources, they really don’t seem interested in making money.
Any recommendations to get me into an affordable, accurate, and easy to use tester? I don’t care if it’s rusty or anything else, if it works reliably . im willing to pay $500-750 ish——-for emissions and conductance capability.
Is this too much to ask?! Where to go? Other advice re. which testers may be moost appropriate, and why, would be more than welcomed,

Thanks so much @cleeds — talked to them a couple times already… They were very friendly! Excellent C.S.
Was going to bump up my high end to $1K, anyway…and, this is right there…a little more with a 6DJ8 adapter. Appears to be an excellent value! |
I agree with cleeds. If you’re looking for an affordable, accurate, and easy to use tester; the MaxiPreamp is one good choice. It does not test for emissions. It does test for transconductance but does not provide a list of what average new tubes should measure. It provides such a list for gain. I’d guess they could explain why they don’t provide benchmarks for transconductance For noise, I run RCA interconnects from the two RCA outputs at the top of the oval at the right side of the picture in the manual into a headphone amp. I don’t know if there is a more direct way to do it. |
