    Sta-2100D vintage receiver. right channel good, tests great. Left channel has problem. On this receiver, you can unplug each individual output board. When I unplug the left channel I’ll put board receiver clicks On And the receiver plays fine. When I connect up the left channel Output, receiver switches from red to green but no output from either channel and then receiver will go into red protect mode. Unhook that left channel again and receiver relays on and is fine. I rebuild both output boards, Can’t seem to track down where the problem might be

    [mod note: some reformatting done for an easier read]

    Welcome to EP :)

    you were asked for pix and schematic, not a repeat of the problem
    you can help us to help you by supplying info asked for :)

    ohhh and it appears that the spacebar on your keyboard seems to have intermittent failure
    it makes your text hard to read when sentences etc all run together ;)

    @tomcat65 Re spacebar problem.
    Suggest a new keyboard (quite cheap things).
    Then wash the old one, strip down and allow to dry completely.
    My spacebarwasdoingthesame until I replaced keyboard. :D
