High Voltage (HT) Power Supply for Valve Power Amplifiers 

Cuales son las caracteristicas de salida del transformador Toroidal que utilizaste para alimentar esa PCB?

The schematic is shown in the video, I haven't changed anything so far but do have some updates in progress and will likely do another video in time.

@@myalbatech The schematic I saw in the video looked to be a single stage, rectified RC filter to a saturated FET capacitance multiplier. Which is basically what you described. But you mention adding additional cap multiplier stages in series. Which would normally result in the full voltage being seen on both legs of the second and subsequent cap multiplier stages. Where as you look to be pulling multiple voltages from the voltage dividers in the tails of the FETs. Which I've only seen possible if they are connected in parallel. Otherwise the FET doesn't saturate, limiting current. Or are the voltages so high that it doesn't matter and the FET stays saturated regardless? So I'm wondering how exactly you coupled the multiple stages together. Which isn't in the schematic I saw at the beginning of the video.

@@brookersmith8278 The FET stages are simply cascaded. Drop the values of R13 and R16 to form a potential divider at whatever voltage you want.

@@myalbatech Interesting. Cascaded, with proper component selection, it should also be possible to achieve substantial voltage regulation. At least at much lower voltages. Ive never played around with that outside of sub 3 volt logic circuits. At these voltages, and with tubes, I'd normally be looking at shunt regulation. But this should make for some fun experimenting in a 2A3 parallel feed SET circuit. Should keep me amused while I'm stuck inside this winter. Thank you much. Looks like that amp measures out well. Hope it sounds pleasing. And if I stumble across anything interesting playing around with this I'll let you know.
