Hello,

I just contacted Maxwell laboratories about a month ago regarding some old
defibrillator capacitors that I needed spec for.  They told me that they
sold that division to General Atomics.  I can't find the fax they sent me
but they're in the same area, San Diego, California as Maxwell, I believe
there in area code 858, so you could try directory assistance 1-858-555-1212
and look them up.

All the best,

Shaun Epp
