[Heathkit] Interesting SB-220 Mods

Tue May 7 20:23:07 EDT 2013

The April 2013 issue of Popular Communications has a nifty article titled,
"A New Lease on Life for a Vintage SB-220 Amplifier for the Radio Amateur".
The author is Peter Bertini, K1ZHJ.

The amp now has QSK, 160-meters and WARC modifications.  But, LOTS of top
and bottom mods to get there.
