Group Buy for Jan's high voltage regulator

Group Buy for Jan's high voltage regulator - update for higher voltage

As suggested in my thread about my high voltage regulator for tube amps, this is the Group Buy thread for it.

I am offering the following half-kit:

- PCB;
- Current source LT3092 SMD soldered to the board;
- overload reset switch SMD soldered to the board;
- Pass device FDP12N60NZ;
- low current high brightness LED;
- depletion mode HV MOSFET IXTP08N100D2.

Everything else is easy to find and/or already in your parts box.

All info for building can be found here: T-reg HV regulator | Linear Audio NL

Update Feb. 2021: T-reg is now available in the diyaudio store!

I thought you already had it working ??

;)

Yes. Not pub ready, but close. +/-400V adjustable, separate adjustable bias, plus as bonus 2x6V for any opamps in the amp.
Uses a specific Antek xformer, hence the PCB size, which sits on top of the Antek

I wonder whether it would need a current limiter?

Hey Jan,

How much voltage drop to operate so what's the Vin = Vout difference?

How much current can deliver?

It can run with 7V difference or so. But you must account for the input ripple. The max output is 7V below the ripple lower peak, under max load.
Current with the shown pass device is about 400mA. Actually it could deliver (much) more but 400mA is about the limit if you want short circuit protection. With lower input voltage, like 300V, probably 600mA, I would need to check the SOA graph.

Edit: This is for the HV regulator. Are you asking about the +/- regulator I showed above?
