Up for sale here is this used vintage Sansui QRX-9001 circuit board. This is from a QRX-9001 but may work on other receivers, though it might need other parts attached to it or other minor alteration. This was removed from a receiver that came out of protection but would not play fully on either channel. It may or may not work, but probably could use the usual recap/rebuild. This is sold as non-working, for repair. Please see my pictures for details.
US shipping and handling is $6, and international is $20. If you have any questions, please ask.
I have more Sansui parts and other vintage electronics listed--feel free to take a look!
