| Planning to build benchtop 500V tube PSU, help needed. |

| TERRA Operative:
I've been planning to build a high voltage bench power supply for a while now, and I have come across the design linked in below. I want to make an old school tube based design, because tubes, and am hoping anyone can give me some pointers as to the design. Are there any modifications I should do to this one before I build it (or is there a better design I should make instead)? I assume there would be a few bits and pieces to update the design a bit since this was designed in the late 60's...... :D As it is only going to be used for tube amps etc, it doesn't need laboratory PSU levels of ripple and regulation, but the better it is, the better it is, until we hit diminishing returns.. Let me know what you think! |

What do you mean it can't be done? Did you see the attachment? |

I'd get an old faulty Tek 5xx Scope from ebay (as long as the transformer works) and make something like this -> https://evilscienceaudio.com/repairs-restorations/tektronix-engineering-power-supply/ |
