FM-220 Replacement Fan & Motor
The FM-220 is a direct replacement fan motor for the Heathkit SB-220 & SB-221. The motor features “oilite” bearings for quiet operation. The motor is rated at 30% greater RPM than the original so it moves a bit more air than the original fan. This new fan motor is the best defense against tube failure due to overheating.
