Product Description

No doubt that this little circuit board (4.5 by 4.25 inches) will make life quite a bit easier for many tube fanciers.

On this extra thick (0.094 inch), US-made PCB with 2oz-copper traces resides a single high-voltage regulator, with its own raw power supply, including the rectifiers and power-supply reservoir capacitors. In other words, except for the power transformers, the PS-2 Solo PCB holds all that is needed to make a superb tube B+ power supply. The PS-2 Solo regulator can power a line-stage amplifier, headphone amplifier, or phono stage. (It might also work in a tube power amplifier, if the current draw isnít excessive.) This high-voltage regulator uses a high-voltage series regulator to achieve a quiet and stable regulated B+ voltage, which can span from 50V to 300V, while delivering up to 80mA of current.

Furthermore, both a full-wave-center-tapped configuration and a full-wave-bridge rectifier arrangement can be used with this PCB. The PS-2 Solo PCB, like the Janus Solo PCB, holds only a single high voltage regulator, unlike the original PS-1 regulator PCB which held both high voltage and low-voltage regulators. Thus, the tube heaters must find their power source elsewhere, such as an AC winding or a simple DC power supply or regulator power supply.

The PS-2 Solo kit comes with all the parts needed to populate the PCB, including the heat sink, standoffs, and 14 voltage-setting resistors, which allows the following output voltages to be set:

50V 60V 65V 75V 110V 120V 125V 130V 135V 140V 150V 160V 165V 170V 175V 180V 185V 195V 200V 210V 215V 220V 225V 240V 250V 270V 300V
