I have an Ayre power amp that would go into protection mode at times, I found out it was a certain rectifier tube if used in my DeHavilland preamp. Changed recifier tube and the problem was solved.
10 gauge power cord. Too much power for tube amp?
Tube amplifiers tend to be sensitive on incoming voltages. Is there a chance a bigger gauge power cord like 10 gauge may not be a good thing?
My amplifier tends to shut down occasionally upon start up. maybe moving to a higher gauge might be better. Does it matter?
