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 provide enough I am thinking ???
Or is that the cause of my problem?
Opinions?

ahhh
Fixed ! The 1K resistor 118 was not soldered on one side!
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 that correct? oh and did you check my labels on the previous question / Photos ? Did I get it right ?

I always put it on the positive side, but I don't think it matters.ChuckD hat geschrieben:What side do I put the 3.9K on the Vu. I read it should be on the negative side? Is that correct? oh and did you check my labels on the previous question / Photos ? Did I get it right ?
Yes, your drawings are right.

How do I connect the Edcors to ground?
Also should my input transformers be connected to ground as well?
Might as well shield everything imaginable first right.
I will also grab some copper tape from work for shielding the power lines.
What else can cause humming.... seems like a grounding problem to me.
