High-Voltage Power Supplies for Tube Circuits

High-Voltage Power Supplies
Power supplies and voltage regulators for high-voltages. Tube circuits, such as line-stage amplifiers, headphone amplifiers, phono stages, and power amplifiers run on low-current, high-voltage power supplies.

PS-Tube
The PS-Tube kit was designed for those who wish to build a tube-based line stage or phono stage—using a tube-rectifier-based power supply that uses a classic tube-amplifier power transformer that holds a center-tapped high-voltage secondary, a 6.3Vac heater winding, and a 5Vac secondary for the tube rectifier.

PS-Tube-SS Kit for Tube Amplifiers
GlassWare PS-Tube-SS kit: simple and self-contained, the PS-Tube-SS PCB holds two cascading RC filters for the high-voltage outputs and negative-bias-voltage power supply and 12Vdc power supply for the input stage.

Tr-PS-2
Power supplies, particularly high-voltage power supplies, are often the big stumbling block to a successful completion of a tube-based audio project. Getting a PCB and all the capacitors, diodes, and resistors needed to populate the PCB is only half the problem. The other half is getting the power transformer. Well, with the new Tr-PS-2 power supply both problems are solved at once, as the Tr-PS-2 holds its own power transformer. The Tr-PS-2's PCB is only 5 " by 2.8 " and, like all GlassWare PCBs, is extra thick (0.094 in), US-made, with heavy 2 oz-copper traces.

Janus Shunt Regulator Kit
The Janus shunt regulator made its first appearance in 2007 in the Tube CAD Journal. In a nutshell, the Janus shunt regulator is a tube-based regulator that uses both feedforward- and feedback-based shunt regulation to reject both the rectifier-induced power-supply noise and the signal-induced power-supply noise from its output.

Janus Solo
Janus shunt regulator without heater PS or heater regulator. The high-voltage regulator uses a pure-tube, feedback-and-feedforward shunt regulator to achieve a quiet AC regulated B+ voltage, which can span from 200V to 300V. Furthermore, either a full-wave-center-tapped configuration or a full-wave-bridge rectifier arrangement can be used. The PCB even allows solid-state rectifiers to be used place of the single tube rectifier.

PS-1 Kit
The PCB is 4.5 by 6 inches and it holds two all-solid-state regulated power supplies, a high-voltage regulator for the tube B+, and a regulator for the tube heaters. Each voltage regulator includes its own raw power supply required for feeding each regulator its raw DC voltage. In other words, except for the power transformer, the PS-1 PCB holds all that is needed to make a superb regulated power supply for tube circuits.
$89.00
PS-2 Solo
The PCB is only 4.25 by 4.5 inches and holds a single, high-voltage, all-solid-state regulated power supply for the tube project B+. The voltage regulator comes the all the rectifiers and power-supply reservoir capacitors required for feeding the regulator its raw DC voltage. In other words, except for the power transformer, the PS-2 PCB holds all that is needed to make a superb regulated power supply for tube circuits.
$39.00
PS-3
PS-3 Tube Power Supply Kit Simple tube power supply kit holds a solid-state rectified, RC pi filtered, high-voltage power supply and a low-voltage regulated heater power supply, with each finding its own raw power supply, including the rectifiers and power-supply reservoir capacitors.
$44.00
PS-4 Tube Power Supply Kit
Simple tube power supply kit holds a simple high-voltage power supply, with an RC filter; and a low-voltage power supply and low-voltage regulator.
$43.00
PS-5 Tube B+ Power Supply Kit
Simple classic tube power supply with tube rectifier and RC filter and heater voltage reference.

PS-6 PCB, parts, and user guide
The PS-6 power supply offers a low-voltage bipolar output (up to +/-50Vdc), suitable for solid-state power amplifier or OpAmps; in addition, the PS-6 power supply holds a voltage quintupler that yields a single high-voltage B+ output voltage roughly equal to five times the rail voltage. For example, if the rail voltages are +/-30V, the high-voltage B+ output voltage will be about 147Vdc; if the rail voltages are +/-15V, the high-voltage B+ output voltage will be about 73Vdc.
$49.00
PS-7
The new PS-7 power supply board is only 2 by 3 inches big. Yet it can pack a punch, as it use two two PS capacitors in an RC filter. In other words, it can be used to make a simple high-voltage power supply for either the B+ of for a negative bias power supply.
$24.00
PS-15
The PS-15 is a new GlassWare power supply kit for tube fanciers. The PS-15 fills a gap: a power supply for those who need a high-voltage power supply with two sets of regulated low-voltage power supplies (usually for powering heaters).
$59.00
PS-17
The PS-17 is a new power-supply RC filter. It is not a complete power supply, as it requires an external power supply to establish the B+ voltage. In other words, it is an add-on for an existing power supply. It could, however, be used with a GlassWare Rectifier-1, which would create complete high-voltage power supply.

This PCB uses five cascading RC filters to provide suitably well-filtered B+ voltage for class-A tube circuits. Each RC filter consists of a 47µF/450V (or 220µF/200V) capacitor and a 3W power resistor. The input and last RC filter are bypassed by a high-quality 1.5µF/550V polypropylene film capacitor.
$34.00
PS-18 Bipolar Power Supply
The PS-18's PCB is small, being only 4in by 4in, but it packs quite a wallop due to the large-valued capacitors used. Two RC-based pi filters smooth the bipolar DC outputs. The heater power supply is regulated, using an LDO regulator, LD1085, and can accept either a full-wave-bridge or voltage doubler or full-wave center-tapped rectifier configuration.

Kit includes 20-page user guide.
$44.00
House GND
The House-GND kit is a simple circuit that helps reduce hum in audio equipment that is attached to a dirty house-ground connection. The diode bridge only connects the two grounds when the voltage difference between them exceeds about +/-1.4V. The small capacitor allows high-frequency noise to find a path to the house ground. The 10-ohm power resistor makes a DC connection between grounds, while still offering some isolation between grounds. The kit is quite small, the PCB being only 1 by 1.4 inches big. Includes all parts, including two hex standoff assemblies and instruction sheet.
