Yamaha receiver, RX 550
repair shop says there is a component in tuner which fails when warmed
up--in fact, in home use here, sound comes out distored after a few hours turned on. Can anyone help with a schematic, and/or tips to track down which component is failing? David |

Sounds like a VCO problem. Maybe an adjustment would help.

I was thinking discriminator, not VCO. Sorry.
