Product Description
TII-Series: Positioning in exceeding totally, not only exceed all the same types of productions that always been imitating on the market, but also to exceed itself.
6CA7-TII is high property audio output pentode, its anode limited dissipation power is 25W, the output power is over 10W when it is used as class A1 in amplifier single tube, and it is over 35W when it is used as class AB1 double tubes.
6CA7-TII is very similar with EL34, which can be replaced by each other.
