Found this on alibaba recently and it looks kinda interesting. They seem to have a fair number of internal pics and even an instruction manual (top right of the page) online so I figured I would post it here. I think this is the first energizer I have seen that requires manual bias adjustment when tube rolling/as matenance which is kinda interesting.
