Gerry;

Thanks for the link. The SB220 had a tap on primary, so when you
switched to CW/RTTY you did not have to retune the amp,
which was probably done by others.

I'll check out the site.

As a note, for information...

The SB-20 was designed to meet the old FCC regulations which
dictated power input, not RF output.
