Leoy...

  Look for that 110K(120K) resistor under the power
resistor behind the HOT. I've had two sets with
multiple failed 110K's...I think they had a batch
problem when these sets were built.
  One of those sets was thermally
intermittant...convergence as you describe was one of
the manifestations of the problem.
