military frequency standard pin out??

Hello Folks,

I found in my collection a frequency standard that I acquired mil surplus at
one time.

The model number of 2N6625-078-4718  internet search yields nothing on this
number.

The unit is a common looking one , approx. 4" x 3" x 4" with an aluminum
cover that comes off.

The cover has the layout of the parts.  The connector has 6 coax outputs
into a D type connector.

It appears 3 pins for power 1 is ground that easy to see but the others are

  1. a  red white and black that leads to the circuit board

  2. and a brown white and black also leads to the circuit board.

I would like to fire this up, but not burn it up.

Any ideas?

Thank you

Good Morning Paul,

Sounds like a very old military unit.  Probably 60's vintage.
before the 13 digit NSNs.

national stock number (NSN) is probably 6625-078-4718.
I do not recall what the 2N could mean.

a modern NSN would look like 6625-00-078-4718  or  6625-01-078-4718

---===========

Remove the 2N from the gaggle and you'll have a standard number sequence that Google has some info
for you.

6625-078-4718  -  * Frequency Standard Module from R-1051* and
RT-618* radios; usable as replacement or adapt to other need where
standard is required. Crystal oven with 5 MHz crystal provides 5 MHz
sine wave output (approx 1.8V) plus possible non-sine outputs dual
500KHz, 1 & 10 MHz. Designed stability: 1 part in 10 / day. Requires
18-24VDC input. 4.4x3x4.5, 2 lbs sh. Used crystal only is checked,
other output may need repair, with schematic,

Found on Fair Radio's site ..
