    Detailed 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. 
     
    KT88-TII is a beam power tetreode, its anode limited dissipation power is 42W. In the audio amplifier, the power can be 100W when it is used as push-pull class AB1 with double tubes, it can also be used in electronic voltage regulator circuit. KT88-TII  is similar with CV5220 and 6550,they can be replaced by each other.
