Batteries NOT included!

In fact batteries no longer exist for this radio.

I will have to build a power supply for this beast!

This will be my most challenging restoration project.

This is old old technology.

Principle: neutrodyne

The Neutrodyne was a particular type of Tuned Radio Frequency (TRF) radio receiver, in which the instability-causing inter-electrode capacitance of the triode RF tubes is cancelled out or "neutralized". In most designs, a small extra winding on each of the RF amplifiers tuned anode coils was used to generate a small antiphase signal, which could be adjusted by special variable trim capacitors to cancel out the stray signal coupled to the grid via plate-to-grid capacitance.

The Neutrodyne circuit was developed in the early 1920s by Alan Hazeltine.

To properly set up a Neutrodyne receiver, not only did the circuitry need to be aligned for peak performance, (that is, getting all its tuned circuits operating "in step"), it also had to be neutralized.

You almost had to be a radio geek just to get it work.

This technology was better than the superhetrodyne of that day and It wasn't until the 30's until there were some major improvements on Edwin Armstrongs superhetrodyne circuit.

Built in 1925 and sold for $9.95

(That was a lot of jing back in the day)

In todays money that would equate to $112.00

I finally did find a schematic for this jewel!
