Pioneer SX-850 Stereo Receiver

Description

Vintage Pioneer SX-850 Stereo Receiver
My first big stereo purchase right out of college and after getting my first job in 1976
I stopped using it many years ago; I don’t listen to FM or play vinyl records anymore, which is all I used it for
I pulled it out of an extra closet, cleaned it up and set it up to check out its functionality. I detoxed as best as I could for what I know about such stuff
I suspect some transistors need replacing (read somewhere that they’re inexpensive and available; repairing is above my pay-grade)
- Left channel scratchy with static
- Right channel sounds fine
- Balanced channels sound good, could be better
FM tuner works
Phono 1 jack works
Phono 2 jack has weak output
Aux jack has very weak output
All knobs and buttons present and working
Cabinet is in very good shape .. small nicks, not very noticeable
I recall having heat sinks replaced around 1980 or so
Owner’s manual and electrical schematic included
SOLD AS-IS
