Pioneer SX-82 Stereo Amplifier
I restored a Pioneer SX-82 which is a late 60's vintage stereo. With it's complement of 29 tubes, 28 watts per channel output, it was a nice challenge. I replaced all the signal caps with Illinois caps (yellow), all the electrolytics, burnt wire-wound cathode resistors in the outputs, many of the tubes along with the Russian 6P15P-EV's in the outputs. I uses those because the original 7189A's are not available and current EL84's would not be able to handle the power out. It ended up with a nice sound and was worth the effort.
