Hi,
does anybody have some spare TO-3 Hp 1884-0019 parts?
they are SCRs or Triacs used in power supply pre-regulators, RCA was
the manufacturer. I need either the real part number or
some HP parts if avaiable. Not listed anywher in my bench briefs, or
on line archives, so any help appreciated.

many thanks,
walter
