Mystery radio -- Philco? - RodB - 08-30-2017

Hi all.  I need some help finding the model of this radio.  It looks like a Pholco speaker, has 2 bakelite blocks in the lower left cotner and the loose tone control switch has a Philco type part number on it.  It is a TRF with 4 tubes; 2-77s, 42 and 80.  Also the parts are stuffed in there.  Just picked it up yesterday for $6.

Yes it is a philco chassis. It is a 59 I believe

I just checked the schematic for a 59 and it looks right on! Now I need a cabinet.

You guys rule! Thanks.

Very similar circuit to the model 84 series just in a pee wee cabinet.

It's a Model 57 chassis. No pilot lamp, and it has an AM/"police" band switch which is loose under the chassis.

Oh, and it is a regenerative superheterodyne, not a TRF.

Ron, Kenneth - Thanks, I appreciate the input. Glad you noticed the dangling switch. I thought it might be a tone switch. Odd place for a band switch!?

The 54, 57, and 58 had it in back, like that. It's just a simple SPST switch that connects a 325 pF capacitor into the secondary of the antenna coil. (In model 54, the switch shorts out part of the antenna coil secondary.) This allows the set to (sort of) pick up frequencies above 1500 kc; this band of frequencies was used in ye olden days by police departments.
