Hi, thanks for letting me join here. I'm looking for some feedback about whether or not I really blew it with my new Mk5 head. I've built tube amps and learned about "conditioning" the capacitors. You start with a variac and go from 10v all the way up to 110v by steps of 10, ten minutes each time. Well... I thought "why not condition my new Mk5?" So I plugged in a speaker and plugged the power into my variac with power and standby on then I did the steps. That's what I did last night and didn't try playing til tonight. Ugh. ...No sound. Waited 4 months from ordering a special build from Sweetwater. All the lights work, the footswitch works, but no output to the speaker, which works and is correctly plugged in. Did I make a mistake trying to condition the caps like that?
