Question choke regulated power supply

Was wanting to build one for my valve pre-amp but not sure where to start.
I have access to parts just really need a schematic/guidelines - at the moment it just uses standard diode / op-amp regulators with cap filtering.
Any pointers?

Model it in PSUD2. Far more accurate than trying to do it longhand.

I think he means a Windoz PC ... i wonder if he would be interested in a port to UNIX, i just loaded up the new X-Code that ships with Panther. I'll probably start with something more familiar thou like a speaker modeling program (i have one in my head screaming to get out).

It seems to run fine under VirtualPC (with the exception that it has a yukky Windoz feel to it )

Default I just want to make it quite clear...

A choke doesn't regulate a supply - you need valves or semiconductors for that. However, a choke input supply smooths quite effectively, and although it drops lots of volts, it draws an almost constant current from the transformer. (If the choke had infinite inductance, it would draw constant current.

It always keeps on surprising me how many people think otherwise...
