A while ago my son, who plays in a band, acquired a quality second hand British made tube amp.
He seemed to be going through power tubes, a matched set of four replaced at a time.
The amp has two ON switches, Power on 1 or 0, and a stand by SW. 1 or 0.
Now intuitively, to me, you would put the Stand by switch on, wait a couple of minutes and then the main power on.
After getting me to look at it after the last failure, I downloaded the manual.
Evidently he (and I) had it backwards.
The main power is switched ON followed by the standby ON after 2 minutes.!
Power down in reverse.
Hopefully this cures his expensive replacements.
Max.
