HEATHKIT SB-200: I have for sale a Heathkit SB-200 amplifier that I would call a project amp. No tubes are included. I have many pics with the cover off.
When plugged in it did have high voltage and that's as far as the testing went.
I have an HL-2200 so I don't need this one. I prefer local pickup and I am located in central Wisconsin
