Shuguang Vacuum Tube 300BS-B (300B)

 

 

 

Triode: 300BS-B (300B)

DESCRIPTION

300BS-B is compatible with 300B, direct heating cathode and medium power consumption. Two triodes can be used in the class A amplification. It is adapted to be used in audio frequency range which requires high output power of 100W. 300B-C long-life design, use pure graphite anode and plate power dissipation can reach up to 60W. If the design parameters are adjusted properly, single tube can use as class A amplifier, and can delivery output power higher than 20W.

 

FEATURES

l          Gold-plated socket pins

l          White ceramic tube socket

l          Carbonized nickel plate reduces reflection of electrons, reserving the original audio signal

l          Filament hooking by using single slice of spring reduces the parasitic capacitances
