Hi All
Well having a look around EBay I can across a pioneer SA 6200 which I snapped up for a mere £22.00 $34.00 I had one of these Amps years ago when I didn’t know too much a about Hi Fi sound then and gave it away. I seen to remember it sounding good at the time so thought I’d have another play with this one for a bit of fun. The seller did say it has a fault in one channel he described the sound as muffled and intermittent anyone have a idea of the cause or causes of this fault While I await delivery of the amp
Intended Work plan is to do a full recap using Elna Silmic RFS and Elna Cerafine Electrolytic and polypropylene Caps in the single path maybe Mundorf MLytic SI electrolytic for the Power supply Caps and a rewire And as I an still a beginner at this restoring game I would gratefully for a guiding hand though the process from the pioneer boffins I’m OK with a soldering iron and reading schematics
But I am inexperienced on the testing side of things like correct currents ext. But keen to learn from the members here and my biggest confusion is soring and selecting the best Transistors equivalents I just don’t know enough about this side of thing I look forward to reading everything you all can tell me about this Amp
OK I had a crack at sorting the transistors would someone pleas advice if I have this right if wrong would you mind posting the best one from this site if possible in stock
