The ground cable (black) that goes to the 601a was indeed loose. I resoldered it and presto! works like a charm again.
Thanks again for being so responsive and knowledgeable.
Time to start getting money into my PayPal account, I figure...
Mike, I will definitely want a Hawk 800-AtomaHawk kit. I think I'll be able to shell out those bucks in a month or so.
cheers

Without having seen the video:
Both the Master Tune and the pitch bend go through the KLM601/KLM-601a (I
recently tried to figure out what was wrong with one of my Poly's). First
thing I would look for is loose wires around the KLM-601 or the points
where it connects to the main board.
(One of my Poly's was missing the whole 601/601a board and exhibited also a
very weird problem that was in some ways similar to the one described by
you: no master tune, and pitch bend only in one direction; and either zero
or full).
If that doesn't help we'll look further.
