MR> TW> One would think so. And it would have been a size inbetween the "AA" MR> TW> and the "C" for the system to be consistant. BUT I so far have found MR> TW> NO trace of it. MR> TW> WHICH brings up another question. WHAT ever happened to the "B" MR> TW> Battery? :-) :-) MR>Well, the "A" battery was used for tube radio filaments in the old MR>days these were likely 1.5 volts but then went on to become 6 volts. MR>The "A" battery changed with the trend. Here is an excerpt from the MR>Old Time Radio FAQ which mentions tube biasing in old radios: I know about thw old Battery Operated Far5m Radio scheme where "A" is Tube Filiment(Various Voltages), "B" is Plate high Voltage(Various Voltages", anbd "C" is grid Voltage. The question is was there ever a Standard Cylindrical 1.5 Volt Battery larger then the "AA" designated as "A" Adn furthewr to muddy thew waters even more since there is a "F" Battery(Tall "D") was there ever an "E" Battery. :-) :-) --- þ SLMR 2.1a þ This note from El Cajon California USA * Origin: Try Our Web Based QWK: DOCSPLACE.ORG (1:123/140) .
