LW;
Thanks for the explanation. I'm still somewhat interested in home stereo Hi-Fi stuff. About 20 years ago I started seriously checking the thrift stores and e-bay for vintage hi-gear, mostly those made in the 70s. The stuff was really well made and designed back then. Most worked fine, only needing pots and switch contacts cleaned well. Even those needing repair was not hard as schematics were usually obtainable and output transistors were still available if searched for. Lots of Marantz, Sansui, Kenwood, Pioneer, etc were being donated as people 'upgraded' to five channel and other BPS (black plastic sh#t) equipment. I would keep the best and sell off the others. Then things started to dry up as the rest of the world started wising up to how great that vintage stuff was and e-bay prices soared on the higher end items. Still have a nice silver Sony component set-up and haven't been able to want to part with the Pioneer SX-1980 (270 watts per channel!) receiver.
