Tube Voltage Regulator, Is it worth the effort

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

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' ..
