Field coil DC power supply help
Considering buying Rullitt field coil drivers again. I was communicating with Oleg Rullit some time ago whilst in the middle of building tqwt for Lii audio crystal 10 that I absolutely love. So put the idea on the back burner. Now the crystal 10 are playing nicely with the Bakoon 11R I've rekindled my interest in the field coils, it's just on my list of things to try while I'm still kicking. I need a DC power supply for these from 100v to 150v DC that can be set at different outputs as this is how the q value of the driver is adjusted. I have a sketch using selenium rectifiers but it's a bit beyond me and a friend commented that it would hum. As its only powering the magnet and nothing to do with the music side of things I don't understand this but like I said it's beyond my knowledge. Bottom line is, can somebody here build me a power supply.

What’s the current rating of the driver coils? I have a couple of toroidal transformers here that might form the basis of a PSU.
