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.

TA050-12 12Vac Toroid
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.
