Yes Bill, I thought you meant me.
Problem is, I sold the amp about 4 or 5 years ago so I can't try anything.
In the meantime, after reading the stuff by Rich Measures, I have also
thought it might have been a parasitic problem. However if you saw how the
guys were tuning it with key-down for long periods, I think you'd agree that
the "user" was a significant part of the problem.
I replaced it with the HF-1000 (QRO Technologies), told the team members not
to run it higher than 750w out (our legal limit here), and it ran forever.
It seems to be "Idiot-Proof".
In the meantime I have replaced the HF-1000 with a Henry SS750HF
transistorized amp, running off a Ten-Tec 9420 power supply. It never even
got warm during the CQWW CW.

Sorry, I goofed. My last posting should have been addressed to Rick, not
Joel.
Carry on
