Looking for Info on Woodstock SA 4000

[chinoy]

Got a working woodstock SA 4000 Amp for peanuts.
It works but has issues.
Its based off 4 x 2N3055 transistors.
Im pretty sure its a copy off some preexisting design.

My interest in this amp is purely to use its phono section which supports both types of cartridges. MM and Ceramic.
Anybody has any info on or schematic for this amp.

So far I have worked on the Power PCB the 1000uf 35v caps were all damaged. Have replaced them with 4700uf 35v caps. x 4.
Next is the pre amp and the tone control board. Then the amplifier board and finally the Phono Board.
If I get some time will post some pics.

restored and working. If anybody has any doubts will be happy to answer questions.
Its a quasi cimplimentry design based on the 2n3055hv drivers.
It uses a 18-0-18 transformer.
Its crystal clear with no distortion. And you will need to change all the electrolytic caps.
Some of the transistors like the BC147B are hard to find.
It has a class A pre-amp and BT board.
