Default 1972 Luxman Sq-202 Schematic

Hi,

I am chasing a schematic for a Luxman SQ-202. I picked the amp up at a fete recently and on close inspection found the main amp missing. I would like to restore it to as original as possible so aschematic or any info on the components used in the amp would be appreciated.

The amp is 35 years old so a major recap could be necessary.
Check the solderings first.

Hi GJW,
The closest I have is the SQ-505x. It's full complementary in the output / driver stage. Uses a varistor and pot for bias current and diff. bipolar input stage. Looks like a push pull vas too. It's a small faded blueprint, very hard to make out. Yours is probably a simpler version of the same.
