@sequences thanks for the info. Thereās a lot for me to digest there.
What i can say right now is that i donāt think i play when the tubes are cold. I mean, the moment the amp produces sounds, itās good to go, right?
Also, i never leave the amp on for long periods of time. Only when i practice, do i turn it on. So thatās about an hour or two per day, if iām lucky. This isnāt always the case.
For the rest, iām sure i need some more investigating. Matched pairs, poison the cathode etc⦠all new stuff iām going to read about.
@AJSki2fly iām going to see what the people at Thomann will say. Depending on that, iāll decide whether or not iāll send the tubes/valves back, but itās a good idea. Thank you.
