Vacuum tube regulated power supply schematic.

Tube power supply a power supply should provide a precise voltage completely stabilized versus perturbations from any kind coming both from the ac source or from the load. The testing circuit on figure 1 is shown. Each voltage regulator includes its own raw power supply required for feeding each regulator its raw dc voltage. 50 to 500 vdc at up to 200 ma for plate and screen supplies of moderate power vacuum tube circuits.

We now have a manageable power supply that can sit on a bench or its equipment shelf. 6 3 and 12 6 vac at a few amps for tube heaters. Vacuum tube power supply design. See below for a picture of the power supply pcb which is glassware audio design ps 1 and has a circuit with a high voltage current regulator paired with a low voltage regulator which supplies the b and a low voltage regulated dc circuit which supplies the tube filaments.

It has no sense to have the best tap if you have only few and spotted water to put through. In order to construct some tube circuits on a breadboard style set up and be able to manipulate or dial up the supply voltages at will i would need to have a bench supply that would put out low as well as high voltages not to mention grid bias voltages filament power and would display what those voltages were. You can read more about the ps 1 here. Well we ve shown that with some plots and a little simple arithmetic we can get.

This is a very quiet supply and excellently suited to our amplifier. I have used the ps 1 in other. 0 to 100 vdc for vacuum tube grid bias. So where does all this leave us.

Figure 10 power supply schematic. 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.
