Hi all

I spent about an hour this morning searching for the manual to the MX-949/U or MX-949A/U tube tester adapter. ?This is a US military adapter that goes with the I-177 tube tester and adds several sockets and many new tubes to test. ?It is vintage 1945, and was in service until at least the mid-1950s. ?

I used to find this manual everywhere, and while Nolan Lee was still alive, I could email him and he'd shoot me a copy or add it to his web page for me. ?It's not on BAMA, but there's a schematic there, which is a good start.

Still, I need the whole manual. ?Any hints? ?Any links? ?

Ideally I'll find an MX-949/U at the next swap fest, but the schematic alone is enough for me to be able to build one. ?But I'd like the manual to go with it. ?

Thanks in advance, and 73
