Hi all!

I have such an amplifier.
My problem with this is that I could rebuild the control panel from the dragster dad1201 drawing I found, but when I assemble it feels like it is drooling, there is a huge amount of resting current and even noisy HDRV (Top of the Rectangle).
If FeedBack is not connected then there is a nice rectangle on the output even after two coils, of course this is not good.
I think the controls on the control panel are good. Ideas? Could they be measurement images?

Same board
