[Milsurplus] 1N21's and 1N23's

[Al Klase]

Folks,

This conversation just sent me to the parts box where I knew some diodes 
were lurking.  The Kemtron 1N23A's, that I have, have a set screw under 
some wax right in the middle of the side of the ceramic body.  The also 
have a set screw in the side of the large gold end that probably hold it 
to a pin similar to the small end.  The 1N23B's and C's don't have the 
screw in the ceramic.

YMMV,
Al
