Hope I didn't screw up but think I did. I biased my tubes in the 25 watt low power mode inadvertainly. Does this affect the biasing process? Of course the amp was all put back together by the time I noticed. I did have the amp volume up and in class A/B mode. Set up for 36 mv, but dumb volume knob was pulled out. Please help really don't want to take amp apart again and hook probes back up.
