You did a remarkable job of "thinking outside the box" with a goal to improve reliability, but I have to ask -- doesn't anyone manufacture high-current Zener diodes? I would think the industrial market would have something on offer.
And what about voltage regulation using cold-cathode voltage regulation tubes? Just saying -- building a tube pre-amp (old tech) could be regulated with old tech.
Walt,
Thanks. As pointed out, the problem was not device current, but heat dissipation of the concentrated assembly. My first choice would have to use the cold cathode gas regulator tubes, but the use of a chassis with a removal top plate and the internal arrangement made that challenging if not impossible to do. If I was starting from scratch, I would consider that, although Morgan Jones felt that the "Statistical Regulator" was a lower noise approach than using gas regulators. So it was a matter of figuring out how to get it done in the tight space I had. I will have to see how it works out. I just hope that I haven't made a mistake in the direction of one of the diodes in the string of 37 per regulator.
