I don't think A and B refer to battery types in this context - but
rather to power _inputs_. IIRC the B supply was the filament supply
and was somewhere around six and a half volts.

Any _really_ old-timers out there who can help with this one?

I'm not a *really* old timer, but did play with old radios while I was
growing up. There really was a "B" battery, it's purpose was to power all
but the filaments, the A battery powered the filaments.
http://antiqueradio.org/bsupply.htm is a nice write-up
