FOR SALE: Heathkit SB-220/221: Heathkit SB-221 as updated to 5 band 220 model. I purchased this item from the original owner. It appears that he originally built it with the SB-220 10 meter upgrade kit. It covers 80, 40, 20, 15 & 10 meters. The band knob does go one click further clockwise to a 10 meter position. I further upgraded it with Harbach Capacitor kit, Softkey, Rectifier board, and bumper feet. Also added improved anode caps and parasitic chokes. Currently wired for 120 Vac but can be easily changed to 220 Vac. Price $1400 OBO. Cash Only! Contact me if you have any questions. More photos available. Some of the replaced parts are included.
