[Amps] Jennings Vacuum Variable Capacitor

[Mark Toussaint]

Hi;

I'm converting an old sb-220 to work on 50mhz. I need
a low value tune cap and want to use a Jennings vacuum
variable of 2-30pf, rating of 5kV or 7.5kV. Does
anybody have one or know of a good source for these
that won't break the bank ?  I know I'll need a low
value of C for the tune, any other thought's or
suggestions ?

Thanks in advance, Mark
