Not too long ago I had an SX-42 to overhaul.  It uses a 3 pf cap as  
top coupling between tuned RF amp stages.  It was shorted and had  
taken out the plate dropping resistor of the driving stage.  (The coil  
in the grid of the next stage was grounded on one end.)

I replaced all the small value dog bones in the set that were standing  
off B+.
