In anticipation of upgrading my DH500 with the Musical Concepts PA-3C driver boards, I decided to check DC offset in my DH500 and found the right channel at .125VDC and the left channel at -.550VDC. I was able to adjust the right channel to less than .010VDC but I cannot get the left channel better than -.220VDC.
My question is can I assume the DC offset problem is on the driver board and if I replace it with the Musical Concepts board the problem will go away.
The Hafler DH500 schematic can be found here:

Thanks for any help.
