Shuguang Vacuum Tube 300B-Z (300B)
Two tubes for a matched pair
Four tubes for a matched quad
Triode: 300B-Z (300B)
DESCRIPTION
300B-Z 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
