The seventies are back !

Hi Gtrdon,

Pioneer SA-500, SA-550 . . . . that's stuff from the seventies.
I found an SX-550, it's a receiver, maybe the amplifier section
is the same. Give it a try.

Thanks John,I don't know which one would be close.But if this helps it uses 2sc2579 and a 2sa1104 in the output.
Thanks, Don Jones
