I recently noticed a buzz coming out of my left-channel, through headphones and speakers, it's not loud.
The buzz stays the same volume regardless of the position of the volume knob.
I believe this is a newer issue, but it's also possible I just didn't notice it before.
I would like to recap this receiver anyway, as it's getting pretty old.
Should I only replace the electrolytic capacitors? Or are there other caps I should look out for?
Also I know there is an 'infamous' transistor in this unit that is known to cause noise, but I forget which one. Could someone look through 'ICS, FETS & TRANSISTORS' parts list on page 18 of the Service Manual to see if they recognize it?
Is the work required worth it for recapping the FM section as well?
I will probably do each section individually at different times and use the receiver in-between phases.
I really appreciate any advice and help you can give me, thanks in advance!
