I am hoping to understand my Fisher receiver. It's never been repaired by anybody besides me, to my knowledge; it was my Dad's and he purchased it around '65. The stereo beacon lamp stopped working, along with a lamp on the tuner slider, the one showing the stations. I was able to repair those fairly easily.
The receiver is fully functional, with some oddities (headphone left/right appears reversed, muting toggle switch is non-functional).
What I am inquiring about is that the right channel has speaker hum, and not the left, and increases with volume increase. The hum is not present when a record is playing (between tracks and quiet passages) and is only present when it is 'idle' (waiting for me to begin another record).
I can easily live with this, as the hum is relatively faint. If this is normal, I have no problem. But, if this is indicative of something I should pay attention to, and there is a way to troubleshoot and repair this I'd like to do that when I have some time.
Do you have any advice for me?
Regards,
Pete
