Product Description

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.

We have many other kinds of electron tubes, such as 5AR4, 5Z3P, 2A3, 300B Series, 6N7P, 6N8P, 6N9P, 6P6P, KT66, KT77, KT88, KT94, KT100, 6L6 series, 5881, 6550, EL34, EL156A, EL34-B, 6146B, 572B, 12AT7, 12AU7, 12AX7, 6P14, etc.
