[AMPS] SB-220 input circuit

[Pete Smith]

>From time to time we've seen posts about how the SB-220's input network is
badly designed for 10 meters, and that results in lower output.

Mine has a relatively high input SWR (ca. 1.8:1 on the part of 10 meters
I'm interested in) and suffers from low 10m. output (ca. 800 watts at
best), but even when I use the built-in tuner on my transceiver to match
the input perfectly, the output doesn't rise significantly.  Why is this?
Is there really no alternative to taking the amp apart to get at the input
circuit and change component values?
