This is a 4 tube superhet radio that runs on a 1.5V A battery and 90V B Battery. In this case, the 2 batteries were contained in the same package.

I have been collecting radio battery information for years. The parts list for the Philco 40-100 calls for a Philco P 60D-11L battery. This battery and its equivalents appear to be the most used battery type in '40s farm radios. An equivalent battery was available from most of the battery manufacturers. Possibly the most sold equivalent was the Eveready 759.

I own a 1946 Motorola 45B12 farm radio which uses the same battery, but which I have not yet restored. I plan to build a battery eliminator disguised as an Eveready 759. I have the artwork for that battery and the socket which goes in the top to receive the battery plug. I will install a socket to match a TV cheater cord in the side of the battery towards the chassis. Looking in the back of the radio with the cheater cord unplugged the radio will appear to be powered by an Eveready 759 battery. With the cheater cord plugged in to provide AC power to the battery eliminator the Motorola will operate.

One interesting note about the Eveready 759 battery is that the battery cable in my Motorola has a 4-pin plug (apparently a JFD No. 707), and my Eveready 759 artwork is for that plug. Radiomuseum has a photo of the top of a 759 with three two-pin sockets. At the ends are two 45 volt batteries, and in the center is the 1-1/2 volt battery. I do not know whether that photo is older or newer than my artwork. I have never seen elsewhere an Eveready 759 with three sockets - only with one socket.
