Harold,

You have a problem somewhere else. The capacitor failing cannot take out the
0.82 ohm resistor. Whether that capacitor is in the circuit, shorted, or open,
it has no effect on the current drawn from the linear, thus that resistor is
unaffected. It is possible, however, that you had a parasitic oscillation, or
perhaps something shorted the capacitor to ground (dust, spider webs, or who
knows what). There is not a lot of dc voltage across that capacitor. If there
were, the section of the RF choke in parallel with it would fuse open. RF
voltage is another issue. At any rate, I would guess a 5 kv unit would work.
Drake made a retrofit kit that replaces that printed circuit capacitor with a
fixed value doorknob. Bill Frost at Drake can give you the specifics. The L-7
is basically a good amp.

73s,
