I just got this amp and am restoring it, should be ready to play next week. Does any one know about it. It's the Peavey VTB300 It's got 4 6550 power tubes, 2 7025 preamp tubes and 1 6AN8 Preamp tube (??). I'm guessing it's 200 watts (4x 50 watts for each 6550??) It looks like it's from the early 70's maybe (but has no serial number). It has really nice components and bombproof construction. I am interested in any information about it the people at peavey have been totally useless, but a schematic would be extremely helpful.
