Sherwood 7450, fuzzy left channel

Hey guys, im stumped. Ive had my turntable setup for a few months now, all was going well, but today for some reason the left channel sounded awful and full of static. My receiver is a Dynacoustic R750(which im 99.9% sure is a canadian rebrand of the sherwood cp-7450). It happens when i play records or when i turn on the radio. It happens mostly when the volumes high but also when its barely on. Happens with speakers and headphones but its wayyyy worse with speakers, barely noticeable if at all with headphones. Also i dont know if this is helpful but whenever i turn the volume down i also have to turn the balance knob about 50% to the left because the channels dont balance at low volumes for some reason. Any help is greatly appreciated :)

Hello, picking up on this older thread:
I have just repaired an 7450 with the same symptoms, right channel with lots of distortion. Sounds good at first and after playing for a few minutes, distortion kicks in. One of the two output power transistors (2SB388 on the heatsink) was faulty.
Replaced all 4 with new ones, recapped the power amp print while at it and now I am blown away from the great sound this receiver delivers. Definitely a keeper. FM reception is outstanding, too.
