BTT: I have a brand new, in the box SK-757f. I'm waiting on my last shop manual to arrive from Germany and then I need to open it up and change out all the capacitors. I've been buying parts (main manual, new belts, speaker surrounds and domes, etc.) over the past few years. I've had a couple of synthesizer and car projects that have been keeping me busy in the meantime.
Use didn't kill the Pioneer, but the years almost did. It is literally brand new, and not thinking clearly, I plugged it in once and saw some capacitor fluid drip from below the right speaker. That was enough for me. I packed it back up, closed the box, started buying parts for it and haven't had it out of the box since. I ended up paying about $500 for the unit back in 2014 when a few of them became available on Ebay as a "barnyard find." Compared with the $200 the original unit cost when purchased at Subic Bay back in 1982, I didn't think it was that bad of a deal. Recently, I've seen these stereos go as high as $2500 for NIB, but to be honest, I can't imagine why anyone would pay that much for one of these. This will be a labor of love project since I got one for Christmas back in 1982 as my first "real" stereo. Ever since it gave up the ghost 10 years later, I've been pining for another one.
I'm probably going to start working on this over the summer and will put up a progress thread.
