The B battery supplied the high voltage for tubes in the early days
Michael Black
}A+ and A- were the filament (heater) supply
}C+ and C- were the grid bias
} Andrew Holme
Sometimes called the "Plate supply".
Rodney Kelp said:The B is from the 2 humps of the half wave rectifier
The B is from the 2 humps of the half wave rectifier.B+ uses the two
positive cycles of the AC signal in a half wave rectifier. B- powersupply
uses the 2 negative pulses of a half wave rectifier.
A full wave rectifier flips the 2 negative going ac pulses to the + side
using the full power of the AC signal for DC. A half wave uses only half the
power.
[email protected] said:Nonsense. As was already correctly said elsewhere, the
"B" designation dates back to the early days of battery-operated
tube (valve) radios, in which the "B" battery was the plate (anode)
supply.
The "A" and "C" designations have long since died out,
You've never seen a 'C' battery?
the filaments and the 'C' the grid bias.
Sure, but not on a schematic as the letter identifying
a power supply.
