I collect and restore stereo equipment as a hobby. I have too many pieces of equipment, this posting is for receivers, I have another posting for speakers
JVC X220 receiver with built in EQ, not upgraded, works fine $50
Sony AV920 nicely featured 85 watts per channel $85
Harman Kardon 395i receiver KH, makes great receivers $75
Harman Kardon 3400 receiver, this receiver uses audio grade capacitors where necessary, many other companies do not do that $85
Technics SA-101 (set1) slight bend on metal mesh that is top back of set, set is fine otherwise $75
Technics SA-101 (set 2) AM band not working, I have repaired this set, works fine $75
Technics SA-300 set repaired and 2 transistors upgraded, 3 LED bulbs, audio path upgrade, no original knobs, levers knobs not replaced as I think this looks cooler. no power switch, set is turned on and off by remote control ! $95
also, not pictured, Pioneer SX-2700 receiver converted to be an integrated amplifier, plus pioneer tuner , amp has cool fluroscan display !!! $95
the pioneer SX-3400 is sold
Also
Pioneer SX-3700 $250
I have updated 8 capacitors in the power section
overall this is a very nice performing receiver in very nice shape
this was third in line of the 3X00 series which went from the 3400 to the 3900
it was not a cheap receiver when new
