Tube Voltage Regulator Design

CarlyBoy · 22nd October 2006, 09:17 PM

Hey Folks,

I'd like to learn more about series voltage regulation with tubes. Anyone aware of a site that has a good explanation of the development of such circuits? Two good ones I'm aware of are John Atwoods's at TubeCad and Steve Bench's.

Thanks for any help.

Why with a tube?

Transistors may be better if properly used.

Hi CarlyBoy,
Any old text books from the early 60's and before will cover this topic. The early Radio Amateurs Handbooks should cover this also. Your listed resources should cover this topic quite well also.

Wavebourn, more than one way to skin a cat. CarlyBoy wants to use tubes for this. Notice he asked in the tube forum.

Are you thinking like 0D3 regulators?

This what you look for?

Bob Pease, a staff scientist for National Semiconductor and a writer for Electronic Design magazine, ran a series of articles on a tube regulated supply and ripple reduction. In the first of the series, attached here, you can see the basic schematic. In the next two articles, he described a novel approach to ripple reduction using feedback to modulate the PS "ground". While this regulator will be too complicated for most audiophiles, it does show how well a tube unit can perform, and might give some design ideas.

And the second article:

Notice I've asked him why the tube, not you. To achieve the same results with tubes as with modern semiconductors a power regulator needs to be much more expensive and radiate more heat. If there are some other reasons to use tubes in regulators, I would like to know them. But I defenitely do not like anymore to read your comments with destructive meaningless critics, Chris. And I assume, nobody likes...

why not create your own thread so the discussion stays on topic?

in relation to this thread, it is stated the reason for this thread is so that creator wants to learn about tube regulation.
