I have aquired two 150w duel channel Sunn Model SA10 Power amplifiers.
Would anyone have any information and manuals and if possible any drawing on these.
These were used for a Cinema 180 setup in the UK in the late 1980's.

Hello:
The SA series amps are pretty straight forward Push pull amps.There are no proprietary parts used so repairing them is a snap. With changing the transformer and filter caps they can produce 300watts per channel into 2ohms. Rock solid and reliable. I have schematics and bias adjust instructions for the 20-0166 power boards. If yours has 20-0135 boards then just go to the service manual area of this site and down load pages from the BETA series amp which used the same power board.

Thanks Don for this info.
I will check which board in the SA10 very shortly
