[Collins] No Drive on KWS-1

[Ed Simeone]

 Greetings,

I recent purchased a KWS-1 that is in fine pyhsical condition but while
tuning up the unit all drive suddenly went away.

We replaced a bad choke in the final drive section and one of the silver
mica caps that was varying with temperature but still nothing. 

There is not even a hint of drive on 80 meters.
All the voltages look good on 40 meters all the way through the final
pre stages but still no drive.
Any clues as where to look next?
