Correct -- but for For what purpose ??

B+ is the positive plate voltage used to draw electrons emitted by the
cathode or filament to produce a useful current through a tube. It can be
supplied either with a P.S. or a battery. So There!

"B" batteries wee a special size used for military/industrial
applications. I don't know if they're still made or not. But there were
never really and consumer items that were designed for the "B" battery,
that's why you never see them.

Not true. Many antique radios used 'B' batteries. I had one once.

"B batteries provided the high voltage to the "plates" of tubes. I
recall 90
volt units.

A batteries provided filament voltage (1.5 volts) to a lot of tubes like
the
1EQ5, where the first digiot indicated the filament voltage, and the
letters
the type of tube characteristics, and the final digit the number of pins
that
were active.
6 AQ 5 was a 6 volt amplifier with two filment connections, a plate
coonection and two grids.
However sometimes there was a cathode too (I'm getting hazy on this
stuff),
maybe the filament didn't count as two."


Ah, I learned something new today. But I stand by the essence of my
original answer - it was very incomplete, though, I see now.

In the beginning every radio, or virtually every radio, was battery operated.
They all used B batteries. It was only later that radio ran off AC line
voltage.

Michael

Tis true
This continued for many years as remote farms had no electrical power
Typical was two 45 Volt batteries

In the VERY beginning, radios used no batteries at all. Those radios were
all solid-state, using a tuned coil of wire connected to a detector formed
by a piece of galena and a "catwhisker," driving a headphone.

In the very beginning, radio used coherers, which could be described as
"granular state". That is, if you don't count the spark gaps Hertz used in
his experiments.

Lots of people listened to radio broadcasts in the 30's and the radios
all used B batteries. There were shoe-box sized "portable" AM radios
than needed B batteries (90v ?). They were in common use until
transisters became practical. I'll guess 1960.
