Quoting Charles Compton <compton3 at centurytel.net>:

> On both of my Astrons, I noticed that the output transistors ran extremely
> hot.  Check to make sure that the thermal compound on the transistors and
> associated insulators is not dried up.  Properly apply fresh compound to
> ensure adequate heat transfer to the chassis. More is not better and thermal
> runaway is not your friend.  This could be your root failure cause.
