Well, let me see...... ::)

8 tubes, push-pull 6K6 GT output.  Transformer power supply with a 5Y3 GT rectifier.  The usual 6-volt tube complement: 6SA7, 6SK7 type setup.  RF amplifier.  Might be a small console by the looks of the chassis.  I'd guess late 1930's.  90 Watts power consumption, rated 105-125 input volts AC.  You can find the schematic on three pages in Rider's 13, starting on page 27. 

I would not plug this radio in to power until all the capacitors were changed, resistors checked and changed as necessary and test the tubes.  It should run a long time, safely, after giving it a bit of TLC.

Do you have a specific question about this radio?
I don't need Google.  My wife says she knows everything.
