Sansui R-50 Receiver bad left channel humming
I have just received a Sansui R-50 receiver that is in excellent cosmetic shape, however the left channel has no audio on a hum as I turn the volume up. The right channel works fine. My question is if anyone in the forum has experienced this problem on their Sansui R-50 and if there is a common fix, I am handy with soldering iron and have a basic understanding of electronics, so I am not afraid to noodle around in the interior of the unit. Thanks for any help in adavance!
