Q: How long would it take to kill a tube amp if the speaker had a shonky connection (maybe shorting)? Q2: If you have a tube amp (B15N) on standby does it need to be plugged in? Q3: When you damage a tube amp this way how is it effected? I'm having all kinds of tech issues right now- basses, amps, speakers, you name it- its playing up. I'll spare the gory details for now but there's a possibility a speaker issue may have caused a B15 issue.
