Hello everyone,

I have the Philco model # E 676 124 shown below; and can't seem to find out what the voltages of the "A" and "B" batteries are supposed to be.  The sticker in the back of my radio says the "A" battery is type P31, and the "B" battery is type P190.

I haven't found a cross reference for these battery numbers to Eveready, or any other manufacturer.

The 4 tubes in the radio are 1R5, 1U4, 1U5 and 3V4.  I read somewhere that the "A" battery voltage could be determined by adding up the first numbers of each tube (Heater voltage).  I haven't determined the "B" battery voltage, but the data sheet(s) on the tubes may indicate this, as it is supposed to be the tube's plate voltage.

What I'd really like to have is the specs on these original batteries, and would be happy to buy dead originals that I could re-stuff or otherwise "counterfeit". Lastly, I'd HATE to guess wrong on the voltages and lose tubes, caps, etc.!

Thanks in advance for the help!
