Silvertone Neutrodyne - 1925
 

I just picked this radio and speaker up during a trip to upstate New York.

The radio is a 5 tube Silvertone (Sears) Neutrodyne made in 1924/1925. The speaker is a Saal reproducer. No tubes came with the radio.

There was even a letter dated 1925 from Sears to the original owner with operating instructions!

Nice and clean.

Nice! Probably a row of 01A's and maybe a 12A for the output? Any luck finding a schematic?

The radio doesn't take 01A's.

The tube sockets are too small. Looks more like 199's.

The radio was made for Sears by King Hinners.

No schematic but very similar to the King Hinners model 10.

The radio takes UV199's - short nubs instead of pins.

I have also posted a pdf of the original instructions sheets at the following:
