The  trouble I find with the fixed, shunt capacitance is they change capacity 
if  they heat 
up a bit, thus requiring retuning. Solution: use a vacuum  variable. Many are 
still 
available on the surplus  market.

This is the telltale sign that I always look for.  Changing  capacitance and 
heating are a sure sign of a cap that is unsuited for this type  of duty.
