These are great suggestions, Mike.

Thanks so much.

Will give them a try.

What would you suggest cleaning the lead terminals and power supply lugs 
with?

I recently had a similar problem with one of my TS570's.

The problem turned out to be an apparently dirty connection between
the power cable and my Astron 35, which caused a voltage drop at the
radio end of the cable.

Cleaning both the power supply terminal bolts, and the ring lugs on
the power cable solved the problem.

The output went from 70 watts to 98 as measured by the TW1.

Someone with a multi meter can confirm the voltage as it appears on
the terminal bolts. The voltage can also be checked on the radio end
of the cable, where it is normal to see a slight drop, but not the 3/4
of a volt drop that I was seeing before cleaning and tightening all
the connections.

Of course, shortly after going through all those gyrations, that newly
cleaned power supply was the one that took the lightning hit about 2
months ago.
