I've had this for decades waiting to either find a matching unit
or use it with a mono tuner. Other than it being built in 1956
have found very little about it on the net. It uses a pair of 6AR5's
as output tubes.

Would appreciate any info and especially a schematic. Considering
pairing it with the EH Scott Phantom Deluxe chassis I just finished.

I repaired one of those back when we were selling
the Sansui SM series of receivers. (SM 80 was so heavy it had wheels)

My director approved repairing it free for the customer
because we wanted permission to photograph it.

Sansui Hashimoto had started in the audio transformer field and they were
offering output transformers and chokes for kit builders in 1954.

Do post a photo of top and bottom and front.

Pics are posted on Audiokarma under the Sansui heading.
Did not realize this was such a rare item so will find another
amp for the Scott project.
