[Yaesu] Crystal Filter Repair

Hi John, 

Looking in my MP Service Manual, on page 6d-1 there is
a block diagram/schmatic of the "SSB-Filter Unit" which
is on a stand alone PCB, not part of the main IF board.

There are TWO caps on that PCB, and listed on the Parts
List as "30 pf 50v SL" ... both are the same value.

<I expect the same values would be on the other filters>

That help?
