I picked up what I think is a radio. Has any one ever seen one and can tell me some thing about it.

The radio is wood with some sort of plastic front. It is marked Day-Fan. The inside of the lid has OEM-7.

There are three large tuning knobs, two smaller knobs, a plug in marked HORN. one marked PHONE and a PULL switch.

The in side has large tuning, (things???) that are attached to wire wrapped coils. There are four sockets but they don't look like any tubes I have ever seen.

The back has one set of two conections, I assume for a battery and a set of five conectors.

Could this be a Crystal Radio????? The man I bought it from said it has a pat. date of 1908 but I can't find any markings

Hi,
Yours is either from 1924 or 1925. I am not sure if it was intended for 01A series tubes, or X99 series tubes (my references add nothing over Rider in that regard.)

Rider schematic is online here:

Yours is probably the 1924 model (OEM7 Supersensitive 1925)

If a 30, or 45 base is too large for the socket (size sample only), it will be for the 99 series tubes.

It actually uses a number of batteries.

You can use a high impedance headphone on the "Phone" jack, or a high impedance horn. If you do not have these, you can use a low impedance speaker with an output transformer ahead of it.

Hi

Thanks for the help. The tube sockets are different than any thing I have ever seen. They do not have pins. They are about 1 1/2 inches wide. They look much like a large bayonet lamp socket with only one slot for holding the lamp in. The bottom of each socket has four tabs about 1/4 inch wide. Do you think I am missing the actual pin sockets or are there tubes that will fit these???????????

Hi,
That is just how some of those were made. You would be using the "01A" series tubes (5 volt filament)- short pin, or long pin will work, just make sure they have a bayonet pin to hold them in place. If you had 4 type "30" tubes with a bayonet pin, you could use these too, just keep the filament voltage to 2 volts.
