Shuguang Vacuum Tube 300B
Two tubes for a matched pair
Four tubes for a matched quad
White Ceramic Base
Triode: 300B-98 (300B)
DESCRIPTION
300B-98 is compatible with 300B
Vacuum tube 300B-98 is new and improved version of 300B. Direct heating cathode, medium power consumption triode is used for class A amplification. It is dedicated to be used in audio frequency range which requires the output power 100W.
300B-C long-life design, use pure graphite anode and its plate power dissipation can reach up to 60W. If the design parameters are adjusted properly, single tube can used as class A amplification, and can delivery the output power higher than 20W.
FEATURES
·Gold-plated grid and tube socket pins
