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.
