Default Yamaha R3 receiver schematics

Hi Everyone,

I am looking for the schematics for the above radio.
I picked up a unit in as is condition at a garage sale. One channel is
distorted, and the other channel gets distorted in about 4-5 minutes of
operation. I have not made any measurements yet, but the protection
circuit does not cut out the speakers.

Thanks, Peter
