Vintage 1976 pioneer SX-650. Largely unrestored but all controls cleaned and everything functions as it should and sounds excellent as anyone who knows the model. The only change I made was the plastic vinyl woodgrian was peeling in places and I always thought it did not do the amp any justice so I did a maple veener all around, stained and then polished the clear coat to a mirror finish and now it looks spectacular!
