SB220 filament winding is on a separate transformer. SB200 is the same
transformer.

I suggest NO diodes or resistors in the LV side of the xfmr.
A buck transformer in the primary loses or looses [sic] the
least power.
The secondary needs to handle the amplifier's
primary current.
????????????
Many Amps, Heath SB220, Many Henry’s, filament voltage is supplied from a
winding on the main transformer.
Anything stuck on the primary will effect all voltages.
