i like this pioneer series alot, but i'd be hesitant to drop $350 on a repair. repairs of 70s receivers is always kinda iffy--i've had some bad luck w/channel imbalances--and working units seem to go for around $400-450 on ebay (the less powerful, but also excellent models of the same series are much cheaper). you might consider selling yours as a fixer-upper and getting a fully operational unit.
Pioneer SX-1050: worth repairing?
My Pioneer SX-1050 will cost about $350 to repair; one of the channels is shot. Is it worth it? Will it cover my Audio Physic Virgos? Its rated at 120 watts/channel. The Pioneer SX series have superb FM sensitivity; my old SX 750 can pick up college stations from my Boston suburban home; 3 high end tuners couldnt.
