Ok I tried a few things all of which made no difference: 1. Connected the center tap secondary of the edcor output to ground. This should have better balanced the output signals in the hope that the two channels would cancel each other out on noise. But it did not work. 2. Shielded the power lines ....

ahhh Fixed ! The 1K resistor 118 was not soldered on one side! :oops: That was easy once I saw way more voltage drop on one side then the other. Got lucky that time but will have to see how it sounds now. Volker, What side do I put the 3.9K on the Vu. I read it should be on the negative side? Is tha...

Well fired #1 up !! So I am getting unequal clipping (only on bottom of wave) on channel 2 at about 3V p-p while the channel 1 will gain up until the transformer clips and whole thing breaks apart way above 3V p-p I measured the heaters to be all at 6VAC. So my transformer is a little weak but will ...

I think ...
