Vacuum Tube Regulated Power Supply Schematic

50 to 500 vdc at up to 200 ma for plate and screen supplies of moderate power vacuum tube circuits.

Vacuum tube regulated power supply schematic.

The testing circuit on figure 1 is shown. The final output voltage is 1 below target final ripple is 2 9µv or 110 7dbv. Well we ve shown that with some plots and a little simple arithmetic we can get. 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.

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. 0 to 100 vdc for vacuum tube grid bias. Each voltage regulator includes its own raw power supply required for feeding each regulator its raw dc voltage.

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 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.

A preamp or an amp is like a tap put after a water tank. You can read more about the ps 1 here.
