[Amps] Henry 4K-Ultra

[Bob Maser]

Latest question for the group:  I notice that there is a 1 pf capacitor 
(C20) that is supposed to be mounted right up next tot he tube.  It is used 
in the tuning meter circuit.  All I have is the top of a porcelain standoff 
on a feedthru cap going down through the chassis.  Does anyone know what 
this 1 pf cap looks like?  I assume that it is not necessary for operating 
the amp but I would like to make the amp complete.

Thanks,
