I have achance to pick up a pair of Lux 3045 monoblock amps. Cosmetically they seem to be ok. However someone in the past tried to convert them to use el-34s connected in triode. The original out-put tube was designed specifically for this amplifier as well as the the out-put transformers by Tim Deparavicini of Esoteric audio Research. The info I'm looking for is 1. Is it still possible to find the output tubes (triodes) for this amp...and 2.I need to find a schematic for this circuit whether, I bring the amp back to stock(if posible), or I'm forced to find a substitute tube. Without a schematic I'm sunk. Is there any help out there? Thanks fastfreddd
