[Amps] Buck boost transformer

[R.Measures]

** Regulation of the anode supply buys virtually nothing except bragging 
rights.   The most critical potentials in an amplifier are filament-V 
and, for tetrodes and pentodes,  screen-V.

>How would it work if you used a plate transformer with a little higher 
>output than wanted. Install the secondary of a small buck transformer in 
>the primary of the plate transformer.
>In the primary of the buck transformer place a resistor of selected size.
>
>Would this provide some regulation of the high voltage?
>As the supply gets loaded the primary current increases and the current 
>in the buck transformer also increases. But the resistor in the primary 
>of the buck transformer would cause the buck voltage to drop. As the 
>buck voltage drops the output voltage of the plate transformer would 
>increase to compensate.
