Again (Still?) I am threatening to do my first actual build.
My goal is the same -- I am trying to build a small PC speaker amp.
Then I got the idea of using subminiature tubes to keep size and PS requirements down. I'd like to use small boost power supplies, as I mentioned in this thread:
http://audiokarma.org/forums/index.php?threads/modern-power-for-tube-projects.843647/
With a little research, I found this, from a 2011 copy of AudioXpress:
(Note error in caption)
Here is what I like about it:
-- "Proper" Push-Pull with a "proper" phase inverter.
-- Affordable, available OPT's ($17.95 each from AES)
-- Tubes seem to be available on eBay.
-- Can build directly on prototyping PC board(s).
Thoughts/suggestions?
