Ah good thought - I have KM1H suppressors in, replaced about 10 years
ago after I tore out the nichrome.

Could be tubes but if you never replaced the old parasitic suppressors
it just may be time. That should be done regardless. I actually have
some NOS 47 ohm resistors and am making clone suppressors of the
originals. That should keep you good for the next 30 years.

Subject: [Amps] SB-220 troubleshooting
My venerable SB-220 is displaying some odd symptoms. On 10M, for
example, the Tune setting for maximum output has changed substantially,
and the output power is down about 150 watts. There are smaller
changes, progressively less serious, as I step down through the bands.
Is it likely that the current pair of 3-500s is failing, or should I be
looking somewhere else in the amp?
