No.Shunt HV regulator

1. The circuit simple, inexpensive components, common.
2. Noise output is very small: -180 dB PSRR at 10Hz to 100kHz.
3. Output impedance extremely small as 0.03 mOhm.
4. The main source of small filter capacitors, at least 66 uF,
small temperature on the heat sink, a small voltage drop on the 30V source.
5. Applications for Amplifier, Pre, phono tube .

No.Shunt HV regulator
V-in: Max: 450V
V-out: 150V to 420V
Current load max: 100mA

Are you selling just the PCB or complete kit with parts? If just PCB, is there a BOM for the parts? Can this be scaled down to 35~40 Vdc?

So how does it measure in the real world?

Found schematic, but no values-p/n for zener D1 and D6?

yes, you can use from 15V
thanks

D1, D6 in the bom

thanks

Can you please point me to the BOM. IS this part of the HQ-IV tube balance DAC GB or are you doing this separately?
