Just for the sake of curiosity, I was checking out some Philco battery circuits, and found an interesting one for a 37-33. Reference to:

http://www.nostalgiaair.org/PagesByModel...013202.pdf

It has the 2V "A" battery, which is straight forward enough, but it also has what's described as a "B-C" battery. If I'm following this correctly, it looks like the "C" section is -3V or -9V, and the "B" is +90V or +135V.

Were these actually multiple batteries? In other words, is the "B" a 90 volt and a 45 volt battery in series tapped accordingly, and the "C" a 3 volt and a 6 volt (or 9 volt)?

I don't actually have one of these radios, I'm just being curious. Thanks in advance.
