Bob,
Bob Waterman sent a suggestion like that and it fixed the proplem. R007,
5.6 ohm, 2w was open. I copied that post and included it below. Have
had several other suggestions from the group, so I send this to the
group.
Thanks to all,
Ken

Bob,
C458 is a 3300@25. Saw that in Winstips. Sure they meant C428.
However, R007 was open.
Replacement cured problem.
Thanks very much.
