multiple power supplies in a modular

[Eric at Svetlana Electron Devices]

This is typical of the kinds of emails I get on the job at
Svetlana. One question after another. All of which could
be answered by the questioner if he would read a few
textbooks and try a few simple experiments. It can be
annoying, that people would rather pump questions than
try it themselves.

It's ESPECIALLY bad in the tube-audio world. You guys
should see the DUMB questions I get inundated with
every day! This is NOTHING compared to audiophiles! :)
