300B PSE Problems
Back from holiday and chilling out after the drive home from the airport with some music, when after one side of vinyl one of my monoblocs emitted a rapid machine gun type noise through the speaker.
After urgently switching off I then carefully switched it back on while keeping a hand on the power switch. After a few seconds I saw a flash at the top of the 300B valve accompanied with a crack from the speaker. I didn’t give any chance for further fireworks and switched off immediately.
I run my amps with just one 300B per side, not needing any more power for my very efficient speakers.
Before I just risk trying another valve, does anyone have any idea what the fault may be or where I should check?
