Tube Voltage Regulator, Is it worth the effort

This thread has some good, solid information and very little bravado.


Special Mention to:
Allen Wright
Bas Horneman

For their interesting contributions.

IMHO, There are several ways to make an adequate Power supply. And several ways to totally botch the job.

In the 1980's, I was totally against using solid state in a tube preamp. However, this was more about not using low voltage devices in high voltage circuits than anything else.
Now that high voltage transistors are available this is not a major consideration.
My first tube amp is going to be a platform to play with some of the discussions.
I want to try unregulated and regulated power supplies. I will probably start out with unregulated choke input supplies.

It is also going to look like a transformer catalog, because this will allow me to experiment with circuits that I have read about and never heard.

    This is a good way to do it: experiment, try different ways and topologies, and document your findings. Hopefully, you do some comparative measurements; it is difficult to judge reports like 'it sounded more deep' or ' this sounded less stable' ..
