Re: [Amps] Topband: Elimination of Treadmill RFI on 160 meters

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.
