[time-nuts] accurate 60 hz reference chips/ckts

[Patrick Barthelow]

PIcked up a couple of  large size Radio Shack  63-960 LED clocks with
Settable alarm, at local Goodwill store. $3.00 ea work great see across
room, loud Alarm, etc...


Barely missed, by seconds, getting a classic Hallicrafters General coverage
receiver
(not like say, S-38) but a larger light green metal box. nearly perfect
condx.  $25.00  with the famous h logo speaker  probably late 50s Vintage.
:-(   Dang...
 Checked LED clocks by ear and eye with WWV, They drift a few seconds in
the course of a few days, and wander back and forth.  Thought AC mains
frequency was tighter than that. They use  an LM 8560 Clock chip.  Uses a
switchable AC mains frequency reference pin  50/60 hz.
Want to provide an accurate  (relatively accurate) 60 hz reference to the
chip.   Some room inside for custom modifications.  Does a TCXO or similar
exist in a small package that provides 60 hz ticks?
