It turned out to be simply a matter of realigning the PLLs - different
board - and only required a small screwdriver, DMM (although I have
better, I used a $16 Canadian Tire meter because it was small and
convenient) and the instructions from the service manual. Took less
than a half-hour and totally solved the problem. No more dots, no more
distortion. It's been running fine for a couple of months now on all
modes.

Dave:
Did you go by the service manual or did you get the instructions from
Kenwood? Do you still have them?
