Re: bombarding trouble ***see video

A few scattered thoughts:
-- I'd guess that two different bombarders, especially one paired with a slide choke and one with a saturable core choke, will dial down and up differently. Are you doing anything to measure output current while you're bombarding?
-- In my shop, touching the manifold while the bombarder is on and opening the main vacuum valve while the bombarder is on are two things that I avoid doing at all costs. You are, of course, free to do whatever you want. But it strikes me as an unnecessarily risk, especially while you're putting power through a tube that is not holding a steady arc.
-- I'll second (third? fourth?) what everyone else has said about long/wet/dirty tubes being fiddly.
-- What are you using to measure vacuum? It seems possible that the "better" pumping set-up is pulling much deeper vacuum, meaning the water/etc is offgassing out noticably faster.
