RE: What to do with 412 volts

Basing a project around a PT is not a good idea.....But I do it anyway. It's a good exercize. You can raise the B+ to ~460v with a better rectifier or anywhere in between 415 to 460v. Low current is your limit. SE 10, 50, or 842 will work. Also SE 45s will work if DC coupled. Suitable filament supplies will be a challenge.
