RE: ok, so now I am really confused.....







I am pretty sure the negative input is not grounded, but i don't think I am going to be able to see anything else the way this thing is put together. Not much room between the board and the bottom. Since it appears there is now not much difference between the two channels sound wise now, I am going to assume for the time being that the switchers are ok and try to get the 26 and the preamp squared away and then listen again. I have attached two scope shots. The first was taken at the outputs of the switcher with a 1x probe, volts/div 50m, sec/div 10us. The second shot was taken with at the outputs of my filter, volts/div 20m, sec/div 10us, 1x probe.
