Gates Radio "Dynamote
Remote Mixer Amplifier
This is a fairly clean example of what "portable" meant in 1947
Your favorite Sportscaster would lug this, and its power supply to the Ballgame, hook-up to a Telephone Line and do the Broadcast.
3 Mic inputs, one Master Gain, Line output and headset jack.
Contains 4 ladder attenuators. Mixing is done at Mic level. Amplified by 2 cush-mounted 6J7s, one 6J7 and a 6N7.
Interstage transformer is a UTC 41-022? (Hard to read)
The output transformer looks like it'll handle 20 watts!
Meter is functional.
Unfortunately, the intrerconect cable for the power supply was not found, so you'd have to make your own to power it up. Not difficult; 4 conductors: 6.3 V filament, B+ and Ground.
Comes with AC cable and a cable with ath large cannon mic connector.

Thanks for looking!
