Shame on these folks for not helping you. The bride and I took a bar break with a hand from the shop. But we're back.
Dan, you will notice in the top left hand corner of the DRIVER BOARD a small hole labeled "Bias". Positive lead goes there. Negative lead on the positive speaker post of that channel. Turn amp on and adjust little blue pot to 350millivolts DC. Do that to the other channel by moving positive lead to the bias test point in the top middle of the DRIVER BOARD, and hegative lead to the positive speaker post. Adjust to 350 ike the first one. Let warm up for 15 minutes adjust both to 385 MV this time and you are done. Let er rip after that!!
