Vacuum Tube Regulated Power Supply Schematic

Each voltage regulator includes its own raw power supply required for feeding each regulator its raw dc voltage.

Vacuum tube regulated power supply schematic. The testing circuit on figure 1 is shown. A preamp or an amp is like a tap put after a water tank. 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. 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. It has no sense to have the best tap if you have only few and spotted water to put through. 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. 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.

Figure 10 power supply schematic. 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. So where does all this leave us. 0 to 100 vdc for vacuum tube grid bias.

You can read more about the ps 1 here. This is a very quiet supply and excellently suited to our amplifier. 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. 50 to 500 vdc at up to 200 ma for plate and screen supplies of moderate power vacuum tube circuits.
