The heaters get DC voltage and the two SRPP circuits get a high-voltage B. Furthermore it had to be a 12Vac design.

A while ago I decided to make my next design an SRPP-based one.
. My existing two other 12Vac designs are big hits as the 12-volt AC sidesteps the wise fear of high-voltageThe most interesting part of the design is the on-broad power supply.
