Tonight I decided to bias the PL14_20 control board. I was going to do that before I installed the DC protect circuit but changed my mind. The instructions were very clear and it was an extremely easy procedure. After attaching my positive lead to the left channel bias test point on the PL14_20 board and the negative lead onto the left channel white binding post I slowly powering the amp up using a variac. I did this very slowly keeping a keen eye, nose and ear (at around 80+or- V I heard the relay kick in) focused on the amplifier's innerds for any abnormalities. That went without a hitch so I then let the amp warm up and when the voltage stopped creeping up (around 0.108 V) I waited another minute and adjusted the trim pot until I achieved 0.355 V. Carefully removing the (+) lead and moving it to the right test point, then the (-) lead to the right channel red binding post, I repeated the process setting it to 0.355 V on the right channel.
Worked like a charm! Now I'm ready for the next step(s). Lee, Joe or anyone looking who knows, do you think I might be able to insert this amp in a system this weekend yet? Brenda's working this weekend and all I've got planned so far is picking up the Ohm Walsh 2's Saturday just after noon. I'm sure I'll stop at one of my favorite haunts for a celebratory slice and a brew for lunch but then I'll be back home again before 2 PM, or thereabouts.
