Vacuum tube regulated power supply schematic. 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. I have used the ps 1 in other. 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.

6 3 and 12 6 vac at a few amps for tube heaters. 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. Vacuum tube power supply design. A preamp or an amp is like a tap put after a water tank.

You can read more about the ps 1 here. So where does all this leave us. We now have a manageable power supply that can sit on a bench or its equipment shelf. Well we ve shown that with some plots and a little simple arithmetic we can get.

0 to 100 vdc for vacuum tube grid bias. The testing circuit on figure 1 is shown. This is a very quiet supply and excellently suited to our amplifier. It has no sense to have the best tap if you have only few and spotted water to put through.

Before the circuit of the regulator will be shown i want to present results of comparative testing of a typical power supply with the inductive µ filter 3 and power supply with the regulator. 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.
