[Amps] HIGH FILAMENT VOLTAGE

[Bryan Swadener]

Yes; a buck/boost transformer with its secondary
wired in series with the OEM transformer needs to
have a secondary rated AT LEAST as high as the
OEM transformer's primary current requirement.

And yes, it will have an EFFECT on the output,
AFFECTing all voltages on the OEM transformer...
it will make ALL the voltages correct.

 ????????????
 
 Many Amps, Heath SB220, Many Henrys, filament voltage
 is  supplied from a winding on the main transformer.
 
 Anything stuck on the primary will effect all voltages.
