John,
Thanks. I'll check that. I hope that is all it is as that is the
same 35 Amp supply that I use.

I had a similar problem with my K3. Suspecting a power supply problem,
and after reading:
http://www.repeater-builder.com/astron/astron-intro-stuff.html
I found that the RS-35M pass transistor mounting screws were slightly
loose, i.e. I could easily tighten them perhaps 1/8 turn.
After adding "split-ring" lockwashers to the pass transistor mounting
screws, the problem has not recurred.
Also, I have added fans to the backs of the heatsinks. The RS-35M no
longer gets hot, like it used to.
