[Milsurplus] Need clear schematic for RT-34 / APS-13 Archie radar

[Jeff Kruth]

Hello All!

In the midst of Ice Storms and covid boredom, I am looking at fixing and firing up an old WWII "Tail-end Charlie" radar. I have two APS-13 and one has not been totally "hammified" so it looks like I could get it going. I have found on-line some mod info from an old surplus conversion handbook including a schematic. However, between said artwork being printed poorly and scanned, its tough to read. It looks like the control box is quite simple and I would start with ginning one of those up. Any one have any detail on the control box? Would appreciate any help at all. If someone had a control box in their pile that was un-needed, that would be super. I know that all it does is light a warning lamp if a target is within 800 yards, but from that starting point, I can go forward with some experiments. Thanks! Jeff Kruth,WA3ZKR
