Hello Frank et. all

I just got the unit Serial: 2024Axxxxx , so i suppose it's a 1980/W24 
made in America.

A nice surprise is the installed 10544A OCXO :-)
The 10544A says "Use insulated tunings tool only" , i don't have a 
plastic or ceramic screwdriver ... Is the message because the "house and 
the inside has different levels" , or is only because the OCXO will 
"jump" when i retract the screwdriver ?. I might have a screwdriver with 
plastic on the shaft. 

For a 1980 unit it's surprisingly clean inside , it must have been in a 
lab or so.

Now i'll check the voltage selector , put the lid back on , and do the 
tests from the manual.

More to follow.
