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.

Hello,
My Commander HF2500, new in 1996, is still working up to spec, including
plate voltage at 2,850 without a load.
Should I consider replacing the filter caps?
Thanks for your comments.
Jay, K2ZT
