What worked and was legal for decades suddenly became dangerous as the pointy
heads had to find new reasons for their existence. Even some ham amps were
shipped that way, notably Alpha, Johnson and Henry.

I guess there is some electrical code that forbids connecting the 120vac
blower between one side of the 240ac line and neutral?
I hope this doesn't start another round of ground vs neutral wiring sins.

You can get more benefit with primary taps and not bothering with a pair of
120V windings; use a seperate 120V line for blowers, LV supplies, etc.
Tapping the secondary limits your KVA as you go to lower voltages and who
the heck needs a CT in a big amp?
