[Boatanchors] RCA AVR-5

[Joe Connor]

I need some help. I'm looking for a manual or schematic for this set. It was an airport receiver from the early 1930s. It qualifies as a boatanchor because it is metal, very big and very heavy.

I believe that the schematic is in the 1934 RCA red book, which, unfortunately, I do not have. 

As always, thank you for your help.
