Title: JB-70
Post by: W5TYZ on February 04, 2023, 09:32:05 AM

I'm looking for the manual for the Signal Corps Junction Box JB-70.
This was part of the HT-4/BC-610 radio set-up. It is used to tie the
transmitter, Speech amplifier, and a receiver into a complete package.
Any help or leads will be appreciated.

This manual contains the schematic for the JB-70 and shows how it interconnects with all the components.
