hello all, I accuired a new 1050 recently. I was horribly filthy outside. Looked like it was in a smokers basement or something. I got it all cleaned up, an it looks great. I deoxed all switches and pots and took all push buttons completely apart and cleaned them too ( that sucked). I have an issue with the right channel not having very much out put at all, unless I turn balance to right and crank the volume. Then I get a distorted but am able the hear the music. I started by checking the power on the power supply board and they seem to all be within 10% of the schematics. I checked the dc balance on both channels and was able to regulate to 0v, went to set the idle current, left is at 50mv and the right is -2.5mv and will not adjust at all? That is all the testing I was able to do today, just wondering which direction to go now. I will print off a service manual at work tomorrow.
