"We" make (or used to make) electrochemical cells as battery replacements
and much of the key development talent is about.  Why are these cells
any better in power supply shunts?  Are they supposed to be lower noise?
Is there any data/information that anyone might want on these cells?

If there is any interest, I have schematics for Dyna tube amps, including
some higher powered (300W) ones that were not offered commercially.
