Product Description

The PS-1 series regulator Rev-B is an all-solid-state regulator designed to deliver between +100V to +300V worth of B+ voltage. The PS-1 regulator maintains a fixed DC voltage and it works to eliminate any AC perturbations on its output. The PS-1 regulator uses an LD1085 as the voltage regulator and an IXCY 10M45S constant-current source to shield the LD1085 from the high-voltage. The LD1085 is nested in its low-voltage span of just a few volts, while the IXCY 10M45S sees the bulk of the input/output voltage differential. Consequently, the IXCY 10M45S gets the heatsink, while the LT1085 is left naked.

The PS-1 PCB also holds a low-voltage, 2.5A regulator circuit for the heaters. The low-voltage regulator allows three different rectifier configurations: full-wave bridge, full-wave center-tap, and voltage doubler. Thus, a 12V output can be derived from either a 24Vac CT, a 12Vac, or a 6.3V to 8Vac transformer secondary. Kit comes with resistors for setting three output voltages: 6.3V, 12V, and 12.6V.

Kit does not include a power transformer, but works with transformers between 120Vac to 260Vac(or 200Vct to 550Vct), with 6.3V or 12.6V windings. The PS-1 can deliver up to 50mA of high voltage and is the prefect choice for a line stage amplifier or a phono preamp.

Triad VPT230-110 toroidal transformer
The Triad VPT230-110 toroidal transformer holds two secondaries and two primaries.

VPT230-110 Electrical Specifications (@25C) 1. Maximum Power: 25VA 2. Input Voltage:Series:230VAC, 50/60Hz Parallel: 115VAC, 50/60Hz 3. Output Voltage:Series:230VAC CT@ 0.11A Parallel: 115.0VAC@ 0.22A 4. Voltage Regulation: 12% TYP from full load to no load 5. Temperature Rise: 30C TYP 6. Hipot: 4000VAC, Primary to Secondary 7. Efficiency: 87% TYP. @ full load

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
