I recently picked up a 5061A surplus, but have no idea whether it works or not. The first hurdle is getting a power cord, but I'm still waiting for the proper connector to show up (the first one I ordered had the wrong orientation on the 3 pins.) In the meantime, I've been reading though what materials I can find online in order to figure out how to try and safely turn it on and see if the tube is OK, or dead.
However after removing the top cover, I can see that my unit doesn't seem to contain the typical kind of cesium tube assembly I see in the HP docs I've found online. Instead, it has a tube made by DATUM with the following markings on the label: Model: 7105A Serial: 9951991226 Part No: 03667-501 Oven Temp: 92 degrees C Oven Monitor Therm: 101 Ohms EMV: 2000 DC NSN ______ 5960 01214 7475 Can anyone tell me about this model and why it might have a DATUM tube rather than the kind I see in the HP oc? Also, any advice on how to safely check it out? I bought this thing out of curiosity but, upon looking inside at all the various dials and switches and multi-turn potentiometers, I find I'm rather intimated by it, even though I have a fairly decent background in electronics.
