The other channel has the different style card. They act the same as no output and no DC on it. R106 is solid 75mV across it. Not sure if I should just changing transistors until I find it or not.
Brandes, you stated that the cards were different, on the card that is different from the one Perry posted pictures of, is there a surface mount resistor on the top left corner that may have bad solder joints?
I don't see anything obvious, I will have to pull the card to really examine it. I don't like pulling them often, before long pads start to come with the cards!!
