Nice. Wish I had that kind of skill. I have a vintage 70's kenwood receiver (very similar to your pioneer) that wasn't stored properly and needs repaired. I tried cleaning it myself but it's beyond my help
Indieman, it's worth it & may not cost you as much as you think. My Kenwood KA-8006 (1974) given to me by my brother needed cleaning, recapping & a couple of small adjustments & I think it only cost me around $65.00. It was worth every penny. Those vintage amps from the 70s & up were truly well made & aesthetically they're great looking. Another thing I was told by the technician who fixed it is that the WPC on the vintage amps & the ones on today's amps aren't the same. I'm not tech savvy so I can't explain what he said but what I seem to have understood is that the WPC back then were more powerful if that makes any sense. Maybe somebody reading what I'm writing who understands this kind of stuff can collaborate what I'm saying. Bottom line is IMHO someone who has a vintage quality amp thinking about getting it fixed should do it. They're a totally different animal.
