This is a really simple but very handy circuit which will provide both a positive and a negative voltage from a single rail power supply. This circuit was originally from a fairly ol...

Isn't a “power supply” that miscellaneous piece of a project that you ignore until you can't anymore, then patch it together as quick as you can so you can get back to the fun parts? And a power supply for tubes? That just amounts to a fat transformer, a bridge rectifier and a filter cap al...
