[Amps] Commander HF 2500

[Alek Petkovic]

No. Not necessarily but what is critically important, is to check the 
value of the resistors across each of the filter caps.

My friend, K4HB, had a filter cap erupt and burn out the section of 
board it was mounted on. He ordered a new set of caps and I advised him 
to check the resistors.

Not a single one was in spec. The one across the faulty cap was open 
circuit.

With new caps and resistors and a repaired board, he is back on the air 
with the 2500.

73, Alek.
