Got this off of Ebay with hopes of converting it to a guitar amp.
Does anyone have a schematic or know the model #? Or am I wasting time?
vintage 1958 conn 2 channel amplifier.

1 channel is push pull 6L6 the other is push pull paralell 12v6

uses 2- 6L6, 4- 12v6, 3- 12ax7, 2- 12au7 & 5u4 & 5y3 rectifiers.

weighs 25lbs and is 21" long.

has rca inputs & level adjustments for each channel. Has input for tremolo.
Any help would be great.

Best advice is to draw out what is there on a full size layout, and from that draw up a schematic. Then you can study what you have and figure out what to modify. I did this on a 1964 Conn power amp chassis with three power amps in it, and decided to make a seperate preamp chassis with three preamps in it, for an end result of three amps in one head. Still working on it 6 years later...haha. It does function however and sounded good in two channels before I decided to redo how I was doing the preamp chassis layout. The layout and schematic that I drew up were invaluable when I was trying to decide what to do with it.
