Just pickep up an SVT 3 Pro Head and a 4x10 HLF. Love this thing. Very curious about the amp. Not much info in the Manual just a block diagram. Anyone here know anything about this amp they can give me some info on? I'm curious how the Tubes set in the circuit? I noticed the manual said some are in the power amp? Phase Inverter? What tube does what? How many Mosfets are in it? Any stuff you can think of that the book dont tell? I love this thing just wonder a bit more than the average Joe.
