[Gary H. Harmon, Jr.]

Does anyone have one excess to their needs or a replacement suggestion?

Gary:

 

This is the crystal for the crystal calibrator in the SX-117. (Probably
other Hallicrafter models as well).  It is marked:  Northern Engineering
Laboratories, Burlington, Wisconsin.  T-9E  100KC.  It is also marked
019-202351 which I believe to be the Hallicrafters number.  It is built in a
glass envelop with an 8 pin octal  base.

 

I doubt I will ever find an exact replacement but you never know so please
keep your eyes open.  It will be possible I believe to substitute a normal
Heathkit (or similar) crystal into an 8 pin base and make the calibrator
work without a whole lot of trouble.  The issue with this approach is that
the 8 pin socket on the calibrator chassis uses almost every pin connection
for wiring hookups inside the calibrator chassis.  Would need to determine
which two pins in the 8 pin crystal base are actually used for the crystal,
and of course no clues in the schematic as to pin numbers.  In fact, the 8
pin connector is not even shown on the schematic!
