[Arnaud - 64]

Hello has all

I would want to have itself a small thing:

I have a VHF module on a FT 726R but I had a problem at the level of the PA
Unit I have a capacitor that set free, that it finds on the exit of the PL.
It is a capacitor that is brown clear with a tip of black on the top.
Do I have on the other hand finds a capacitor that is all green, a green
with a tip of yellow on the top, and an another one that is brown clear with
a tip of orange on the top, do capacitor make the same value 15pF on the
other hand has what corresponds colors of capases?
Is it possible of brings up one of capacitor?
the reference of the HS capacitor  is: ceramic 50Wv, what do 15pF have
corresponds 50Wv?
thank you for your help
