I just bought another Pioneer SX-9000 Reverb Receiver on ebay for $65.50 plus $21.50 shipping. This one is cleaner than my old one and comes with the original manual PLUS all SIX of the stupid looking special Speaker plugs, which cost dang near what I gave for the Receiver.. Those old "Verb" Pioneers are rated at 240 wpc and kick assss with the dual volume controls and other levers, knobs and buttons. I have a pair of JBL 15"s, a pair of Fisher 12's and a couple of audioxox bookshelf speakers and my old Pioneer SX 9000 made my prostrate quiver and my feet numb from the bass..
Maybe thats why it won't power up completely anymore. It was always slow to amp up, but now all the lights work, but no FM reception or power out. The fuses are good and the reverb switch makes the speakers bump when I turn it off and on. I think its a relay or circut breaker that won't switch on.. Anyway, there were three of those on ebay a couple days ago and there is one left that looks real clean but the tuning needle do-hickey fell off and the bid starts at $49.00 .. If I had the money handy I'd pick up on it too! For the money those old receivers are Impressive and Heavy built.. many boards, wires, caps and nice wood cabinet..
