Hi Dick,

According to the SB220 schematic, each circuit breaker feeds one primary
winding. IOW, just fine. The problem is, you need a STIFF 120V source to
avoid dynamic instability of the HV. My SB220 plays much better on 240V.

Hello list,
I've had an SB220 in the past and am looking for another one, but I will
have to run it on 120 volts, How does the 10A breaker handle the change?
I've never heard of anyone changing the breaker...de Dick NY1E
