Just reached 95% on the RS-2010. Am a sucker for vintage equipment and any unit that hits the triple digits on the WPC. Found this unit local really reasonable about a year ago or so ago. Cleaned up & replaced all the lamps to LED. It sounded nice and decided to send to my father in-law = to give him at taste of vintage gear. Was slightly worried that the STK packs might fail as some point... he purchased some 8 ohm Boston A100 speakers. After a few months it stopped working - likely one too many Miller Lites one evening. Since he enjoyed the stereo, I decided to rebuild and give him one of my unicorns (Realistic STA-2100). The Fisher made it back to my hands at the beginning of the month. Turns out that one of STK-0080 was blown - no surprise there. RCS16 and others came up with a kit to replace the STK-0050 modules.... and I thought this would be good test bed for the STK-0080 (which appeared to within the realm of the kit) . Bought the kits off fleabay and built them = thanks to RCS16 for his help. More post to follow.
