;-) Never mind... I found a bias posting on TNT that helped me out and got them adjusted. I can't seem to get the left chan DC lower than 30 now that the bias is set. set. I set the bias to 15 (thus 30 for both). I also tried 25 (50 for both) but no difference. I am going to test the VR's if I can remember how and probably order new better ones if I can figure out what to order. Any advice would be appreciated.
