[Milsurplus] Wanted.

The Z1 trap in my Collins 488-A2 inverter has  become deceased....
it's supposed to make sine AC out of  horrible stuff. I use it with a
618T but also on  ARC -38 etc.
Any one got a wreck?. The trap/filter is made by Varo and  won't sell
direct and Collins spares  have a communication problem!
BEARINGS. I've always wanted to ask/know how ball bearings are made...
always seems  a bit like those Chinese puzzles how they get the
balls/rollers inside and with such a fine tolerance so they don't
rattle about and come out.
Not  radio, but an answer could be enlightening.
Cheers
