B. The amp sounded like it was lacking punch and balls which was the reason for the tube change. The last tubes in there were junky Groove Tubes in the power section and possibly the stock preamp tubes. Figured that some nice JJ's and a little hotter bias would breathe new life into it. My Carvin combo (sans speakers) into an old Peavy 4x12 has been KILLING his Marshall :p .
C. Yes, I am aware of the deadly voltage :eek:
