[Heathkit] Need info on SB-220

[Jim Brannigan]

I second the Harbach comments.
You should also consider replacing the Filter Capacitor Block and if you are
going to use it with a modern (post 1980) transceiver you will need the
Soft-key module to protect the keying circuits in the driver radio.

The SB-220 is a fine amplifier.  With new capacitors and the rectifier board
it will provide years of trouble free service.

Happy New Year
Jim
