~180v regulator schematic needed!

[My Uncle Napoleon]

I want to regulate a 180 volt (less than 1 ampere) for an OTL amp. any help is appreciated

What is the feed voltage?

right now I'm feeding 155v to the circuit, that's adequate, I want it regulated. if some volts will be consumed or missed in the regulator, I can wind a new tranfo, 200volts for example.

You can use the Simple series reg, it has been tested from less than 100V to a few hundreds volts (and simulated at up to several kV). It drops a few volts, but rather less than comparable alternatives.

I have also described some LDO HV regs, but they either require a PMOS, or regulate the negative rail

uh that sounds good. is there any schematic or link or thread or something about what you told?
