Tube Amp Power Supply Schematic
All of this leaves us with the following power supply design.
Tube amp power supply schematic. For those of you who don t recognize it this is a thermal relay in an octal socket. Ac wall power from the power cord flows through the on off ac switch and on to the power transformer shown at bottom center which steps up the wall voltage to 325 volts rms root mean square average ac for the high voltage supply and steps it down to 6 3 volts for the preamp and. This is a rather old technology gizmo. Help with nixie tube power supply common ground hot mosfet.
When calculating the max power supply needed for an tube amp and using the formula v max supply vo peak vd transformer voltage regulation line land variation vo peak 2 rl p 2. Spectrum tube power supply. Analog mixed signal design. The final output voltage is 1 below target final ripple is 2 9µv or 110 7dbv.
A choke input power supply is approx 90 efficient therefore the b will remain relatively stable when a class ab amp is driven at high power. It has no sense to have the best tap if you have only few and spotted water to put through. There are hundreds of pages of tube amp information on my library page. 16v valve rectifier loss is small compared to b 560v.
Calculating power supply for tube amp. Oddblocks power supply schematic part of diy is that you can do things that manufacturers won t. Figure 10 power supply schematic. Vd voltage lost across the tube would vd be the voltage across the plate resistor or what.
Please visit my tube amplifier forum here s the place you can go to ask tube amplifier questions. That s it for the signal path now let s examine the amp s power supply shown at the bottom of the schematic. In the above circuit 16v loss is caused by the forward resistance of the 2 large valve rectifiers. Inside the blue.
This is a very quiet supply and excellently suited to our amplifier. Power supply for vacuum tube pre amp. 12sl7 kt88 tube amp power supply schematic figure 2. I found a source for 6no30 tubes.
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.
