I am the proud owner of this Heathkit SB-220 Amplifier
It was built around 1971 by a good freind of mine. I am only the second owner of this work horse.
It has already had the newer fan installed, but that's about all. I am going to (are already have) repaint case as well as install new front panel.
I am also installing the newer rectifier / metering board from Harbach Electronics, plus the Parasitic Suppressor Kit from R. Measures.
I will update this page as progress is made on this project.
