I have an SB100 in my to fix pile. I plan to refurbish this and upgrade it to SB102 revision wherever possible. This saga will be presented as a blog as if you were watching over my shoulder as I work at the bench. I used to do a lot of these radios when I was working. They are a good example of Heathkit making SSB affordable for a lot of hams including me.

In the mean time, I will point you to a Heathkit aficianado who has done some excellent work on the SB104 as well.
