I saw angus tech say thisDon't bias to numbers. Bias to tone.
(just don't do it while playing guitar)

Yep. If you bias too high - you'll know. It won't sound good starting with a 'warbling' sound. I've found.This is what I've always done. Haven't had anything blow up on me yet
Yes, it will sound like shit biased too low....or too high.Yep. If you bias too high - you'll know. It won't sound good starting with a 'warbling' sound. I've found.
I mean, I order tubes matched to a spec that I already know is what I want. I may put the meter on to check how well they are matched but I like plug and play. That is the downside of buying used tubes IMO. Unless you have the same plate voltage as what I have, your bias numbers don't mean much to me.
Usually the case, but some amps can be weird about that. The Gjika by default was close to 60ma with my bias meter (I never took out the chassis or messed with it). Might be because it’s class A? Not sure. And my Uber is recommended in the manual to be 22-28ma. Maybe since it’s so high gain. In some amps high 20’s sounded good to me, but yes usually somewhere 30-40 in most ampsYes, it will sound like shit biased too low....or too high.
But, the magic number of 30-40ma usually works with any amp I've ever owned..with 600v PTs down to 400.
