I have this cool hamfest acquisition that I would like to get working but I can't find any information about it. It's a Tracor 401A clock, a solid state rack-mount instrument with 100kHz input, various divided down outputs, a Patek Philippe 24H analog clockface, Nixie tubes for seconds, and sporting an old USNO property tag. Circa late 1960s. I expect its function is very similar to the HP113/115 clocks. However the power cord is cut and I'd like to check out the power supply before I let any smoke out... Anyone have a schematic or manual for this thing? Thanks.
