[Collins] Frequency drift/variation in KWS-1

Amen.

Replacing the 5U4GB at V108 worked for me after two weeks spent discovering, 
with Tony's guidance, why the +275 was low.  Changing the tube stopped all 
variation and warble, (and blackout of the VR tubes).

Best to all.

<< I have now found two cases of PTO variation/warble/drift in  KWS-1s with 
the 
same root cause: The 5U4GB at V108 gets tired. This results in the +275 not 
staying stiff enough for good regulation from the gas regulator tubes on the 
PTO.

If you have excessive drift/variation, try a fresh 5U4 at V108...
