Tube Mic Power Supply Schematic

Unlike most tube mic power supplies on the market ours does not use diodes to set the output voltage.

Tube mic power supply schematic.

The voltage drift causes nonlinear behavior from the mic s vacuum tube which in tu. A kit is available though my company which provides circuit boards and key components that would be difficult to source. First if you know that you ll be using line level signals all the time with the tmp then you can. So where does all this leave us.

Nice back up power supply for mxl tube mic or any other tube mic that is one pattern it s all i have to say read more. The following diagram is the circuit diagram of tube mic pre amplifier 12ax7. Product information item weight 3 2 pounds product dimensions 6 75 x 4 15 x 2 5 inches. This circuit is little hard to built.

Diodes add noise and allow the output voltage to drift. Tube mic pre amp circuit electronic. It has no sense to have the best tap if you have only few and spotted water to put through. This is a very quiet supply and excellently suited to our amplifier.

Replacement power supply for mxl v69 tube microphone. The vps1 kit lets you build a premium power supply for your tube microphone. The 12vac needed for pin 5 of the 12ax7 can be obtained from point g while pin 4 should be connected to point a. 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.

Well we ve shown that with some plots and a little simple arithmetic we can get. A preamp or an amp is like a tap put after a water tank. All capacitors with value of 33uf are 16v while the all others are 50v unless marked otherwise. There are two options for line level signals.

Vacuum tube power supply design. The result is a two channel tube mic pre featuring jensen input output transformers optional phantom power input pads and regulated supplies that can be built for about 400 in materials.
