Tube Power Supply Circuit

The ps 11 includes both the rectifiers and power supply reservoir capacitors.

Tube power supply circuit. 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. 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 series dropping resistor drops the output of the supply to 250v. The output of the rectifier is filtered by a c r c upside down pi filter.

Power amplifier with tubes often become the choice for a small slewrate so that the resulting audio quality is guaranteed. The first step is to determine the total load for your power supply. 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. A preamp or an amp is like a tap put after a water tank.

The next power supply is virtually identical to the one above except it uses a 6ax5 rectifier tube instead of a 5y3. The 6ax5 does not require a separate filament winding. If you want to repeat this project please. Let s make a bench power supply.

The power supply in the 6146b transmitter is a design commonly called an economy supply. B power supply circuit. The third winding is a 600 volt center tapped 300 0 300 v winding that is rectified by a 6x4 vacuum rectifier. The 5y3 gt rectifier filament is powered by a separate 5v ac winding on the power transformer and the tube filaments and dial lamps are powered by another 6 3v ac winding.

It also warms up at the same rate as other tubes which many people feel is much easier on filter capacitors. 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 design makes use of the power transformer and rectifiers in a very clever manner. Tube power amplifier 35w in the circuit that is required to supply a high dc voltage is 220 vdc ddengan order to work properly.

This is the b voltage required by your amp and the total load current for all plate supply and screen supply voltages. The ps 11 circuit board makes life quite a bit easier for the tube fancier. Part 1 the basic power supply power supply constraints and choices.
