Thankyou very much for the info. This is exactly the kind of response I
like to get when I post a question. Very informative. Now I propose
another question.... my buddy may scrap the thing if it costs too much
for repair. I'm fairly new at repair, but am charging friends
replacement and shipping costs for repair only (no labor). I do this
for the learning experience. If I ever total srew up a peice of
equipment, I am willing to pay for it. I figure this would be the cost
of my training. So.........I do see how to dis-assemble the sub deck
(already have the drive assembly removed), but I was unaware of built
in anti jitter software. I will research for a replacement motor, but
would you have any more info on how to access the jitter software and
it's use? Thankyou again.
