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)

Many customers ask us about the sizes for installation, here we provide a table for you information.

Output transformer used in HIFI tube amplifier is a key component in high-fidelity audio equipment, it utilizes electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core. In electrical equipment and radio field, commonly used as lifting voltage, matching impedance, safety isolation and so on.
