jpc2001 Posted March 1, 2017 Share Posted March 1, 2017 (edited) Pioneer SX-850 stereo receiver. Good condition. Pretty face, minor knicks on the cab. I replaced transistors on the protection board, which fixed a problem with the protection relay opening sporadically. Also I changed out the bias pots and the power amps' input transistor pairs, and set the bias. I replaced tantalum coupling caps on the preamp with oversized electrolytics. (Tantalums sound bad.) This one is all running like it should now. It's clean inside, with no evidence of a major repair or rebuild. One of the output transistors is not original but it is a correct replacement. Built to last ten lifetimes. Has two pairs of output transistors per channel, which allows it to supply more current than its 65-wpc-into-8-ohms rating suggests. Asking $250.

jimjimbo Posted March 1, 2017 Share Posted March 1, 2017 Photos definitely will help your sale. The SX-850 is the excellent "sleeper" unit in that line. Quote Link to comment Share on other sites More sharing options...

jpc2001 Posted March 2, 2017 Author Share Posted March 2, 2017 PS. I'm not interested in shipping, sorry. Too much risk of damage and/or fraud for me. Quote Link to comment Share on other sites More sharing options...
