WAD 300B PSE Problem
Where to start looking?
One of my monoblocks has a fault which appears after about one hour of use when the signal collapses to a muffled and distorted low level. So far I've swopped over the power valves and the rectifier valves with no change. I'm just about to swop the smaller valves but very much doubt that will reveal anything.
Has anyone else experienced this problem or has any guidance on where to start looking?
Thanks,
Paul.
PS I run battery bias on V1 and with just a single 300B
