What is B, P, G for tube amplifier output transformer?
What is B, P, G for tube amplifier output transformer?

The primary of tube amplifier output transformer generally has two, three and five connection terminals.

 

The circuits of single tube type class A amplifier Among them include:

  1. The primary is 2 connection terminals, P is connected to the screen, B is connected to B+ (that is, DC high voltage power supply)
  2. The primary is 3 connection terminals, P is connected to the screen, G is a Ultra-linear tap (connected to the second gate of the power amplified tube such as 6P6P, 6P1, 6P14, etc.), B is connected to B+ (that is, DC high-voltage power supply)
