Tube Power Supply Circuit

The positive of this supply is connected to the negative of the pass tube power supply which connects to the b c output terminal.

Tube power supply circuit. On this small three by six inch extra thick 0 094 2oz copper traces usa made pcb resides a high voltage power supply suitable for powering a tube power amplifier. This is the b voltage required by your amp and the total load current for all plate supply and screen supply voltages. B power supply circuit. The ps 11 circuit board makes life quite a bit easier for the tube fancier.

The output of the rectifier is filtered by a c r c upside down pi filter. The ps 11 includes both the rectifiers and power supply reservoir capacitors. The next power supply is virtually identical to the one above except it uses a 6ax5 rectifier tube instead of a 5y3. Tube power amplifier 35w in the circuit that is required to supply a high dc voltage is 220 vdc ddengan order to work properly.

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. 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 output is smoothed by a pair of filter capacitors and a filter choke. Part 1 the basic power supply power supply constraints and choices.

This design makes use of the power transformer and rectifiers in a very clever manner. Let s make a bench power supply. The power supply in the 6146b transmitter is a design commonly called an economy supply. If you want to repeat this project please.

The first step is to determine the total load for your power supply. All four diodes are used to form a full wave bridge rectifier for the plate supply but for the screen supply only diodes d1 and d2 are used. A preamp or an amp is like a tap put after a water tank. The third winding is a 600 volt center tapped 300 0 300 v winding that is rectified by a 6x4 vacuum rectifier.

It also warms up at the same rate as other tubes which many people feel is much easier on filter capacitors. It has no sense to have the best tap if you have only few and spotted water to put through. A series dropping resistor drops the output of the supply to 250v.
