[AMPS] runaway amp.

[Lamb]

I now recall working on an Alpha 77 that had a similar problem.  Power
output creeped upward.  After awhile, the amp became very efficient.

It took a bit longer than it should have taken for me to realize that the
dummy load was heating up and increasing in resistance.  There was no
increase in power at all - just meter readings.  I then measured the dummy
load and learned that even cold it was over 55 ohms.
