Interested in one neon sign transformer (probably 9000v, 60ma), and perhaps one or two 10cm focal length lenses.

Thanks,

Heh, the secondary isn't going anywhere... yet.

I'm just cleaning house because I know I'll never use these parts, and electronics has become fairly boring lately. Maybe it's just the winter laziness... I dunno.

@AAlasers, I'm keeping the 60mA ones, but the 30mA ones can go. As for the lenses, $18 takes 2.

Added more stuff for sale too.

Well outside of outdated and shunned photographic processes or making your own thoriated lantern mantles it is a rad (radiation) source useful for mostly alpha and gamma spectroscopy. The problem here is that it is a powder, which makes it a high contamination risk, especially if handled by a novice, or worse, someone who doesn't know what they're doing.

BTW, the lead box and one of the 7.5kV NST's has been grabbed by yours truly, so it is no longer available.
