New Shuguang 300B-98 Red Flail Base Tube Audio Vacuum Tube HIFI Valve for Amplifier
Description:
- 300B Series: Straight heating cathode middle power double tridoes used in the amplifing of A1. It is adapt to be used in audio frequency which needs the output power is 100W.
- 300B-C long-life design, use pure graphite anticathode and plate dissipation power can reach 60W. If you adjust the electrical route properly, single tube can amplify A1, and can get the higher output power than 20W.
