[Yaesu] From CO8LY

[Dr. Gerald N. Johnson]

Your new capacitors sound like they are general purpose ceramics and 
aren't big enough to carry the RF current in the PA cathode and are very 
temperature sensitive. You need ceramic with temperature characteristic 
NPO and with a 3/4" or larger diameter with heavy wire leads to carry 
several amps of RF current.
