There was a distortion on the left channel of my AU-101 so I recapped, then went through replacing the transistors... the distortion on the left channel seems to be gone but now the right channel makes some quiet, distorted, semi-musical buzzing when I turn the volume up, and not much else.
Reading through other posts, I thought this might be a Bias problem so removed the fuse to check Bias (as advised here: http://audiokarma.org/forums/index.php?threads/sansui-au-101-bias-adjustment.435511/ ). The reading on on the left channel was fine (circa 10.0mA) but was 0.4mA on the right channel. It gives a pretty similar reading not matter how far I turn the variable resistor.
Any suggestions about what this might mean and what I should try next? I've checked the fuse and orientation of transistors but I'm n00b to all this...
