This Noratel toroid offers two 12Vac @ 2.08A windings, which can easily be placed in parallel, yielding 4.16A of AC current, which rectified equals about 2.3A of DC current for either 12Vdc or 9Vdc power supplies. Or, if you need a 24Vdc power supply, the two 12Vac winding can be placed in series. The transformer holds two secondaries, so it can be used with either 120Vac and 230Vac wall voltages at either 50Hz or 60Hz.
The Triad VPT230-110 toroidal transformer holds two secondaries and two primaries.

The two secondaries allow two rectified B+ voltages to be created, either 165Vdc @ 100mA or 330Vdc @ 50mA. The two primaries allow this transformer's use with either 120Vac or 230-240Vac wall AC voltages.
This toroid is a great match with the PS-1 regulator, along with the TA050-12 12Vac toroid for the heater regulator portion of the PS-1. I should know, as I have used many of these toroids in the past. It could also be used with PS-3 or PS-15 or PS-18. It would also work well with the ACF-2 PCBs.
Because we charge a flat-rate of shipping, you will not be penalized for its high weight (1.102 lbs). This high-voltage toroid comes with the mounting hardware and large rubber washer
