Re: New Old Amp Day
Yes guys it is the blackface ab763 circuit from the factory. This amp just had the original speakers reconed and had new tubes & bias, caps, etc. the amp tech for Duke Robillard went through it for the previous owner, who had it since new. It has seen a lot of gigs but it is in great shape. The guy even gave me the old preamp tubes that were still good, old sylvania tubes. I feel I really scored a good deal at 900 bucks. It sounds fantastic! The breakup is so rich and fat and the clean is just beautiful. I think that I may take the 12at7 reverb driver tube and swap in a 12au7, the verb comes on pretty strong and the sweet spot is 2-2.5 I am hoping the 12au7 will just give me better control over it. Other than that, it's all good. The power tubes are new JJ's and they sound pretty darn good. But of course I'm hunting down a good pair of old RCA's and I bet I won't be disappointed when I find them!
