I'm just going to have my own mini trivia thread here.
I looked closer at some schems last night with them at the same address, but seperate company nanmes..
Challenger was using the same in-house part #'s.
I looked at a Challenger 807 PP amp and the OPT is T256.
On a 1949 Bogen 807 PP the OPT is T256-1.
I don't understand the system, but they are definetly sharing more than office space.
