I am the person who asked the questions and I wish to thank you all very much for your kind replies and help.
This is a hobby for me. I am a retired engineer from Intel in Portland, Oregon and have moved to Bellingham, Washington.
I don't care how long this will take to learn and execute and I don't care if the first 100 tubes/amplifiers will fail. This is to be a journey for learning for me.
I have been known to make stuff that takes a long time to make and do not have corporate/commercial marketability.
As I have no boyfriend; no girlfriend; no husband; no wife; no kids and no pets; and TV sucks and Hollywood sucks and sports to me is riding a bicycle of kayaking and not watching a bunch of millionaires bashing into each other on a green plastic carpet under bright tv lights; I have the time and my entertainment is myself doing these things.
To tell you the truth; once my journey is over and I have a working amplifier; I will most likely give it away or put it onto the shoulder of the road for free and then move onto the next project. It's the process and not the final item that lures me.
Humbly and respectfully yours,
