    Product Description
    Brand Model : Amptata T4
    Global voltage standard ( 100V~240V )
    Octal 8pin probes cable lengh: 55cm
    T4 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
    T4 can test many types. At present, we have 8pin and 9pin probes options
    This listing T4 suitable for EL34 KT88 6L6 6V6 5881 6550 KT66 KT100 KT120 7027 etc.
    T4 can get the reading direct from the pointer-type current meter. It does not need any convert from mV to mA
    What's in package?
    1pcs T4 Tester Body
    2pcs Octal 8pin Bias Current Probes
    Note:
    Keep the amplifier silent during use T4
    Turn off speaker sound,Do not turn on sound play songs
    Insertamplifier just is let the tube get power and warm up
    Read most accurate's tube cathode current in working state
    How to use it?
    01: Turn off amplifier.
    02: Remove the tubes then plug in T4 tester probes socket
    03: Then plug T4 tester probes in amplifier socket
    04: Turn off speaker sound turn on amp (Keep amp silent) and let tubes get warm about 5 minutes.Just turn on the amplifier without let speaker sing
    05: Read the bias measurement
    06: Two pointer-type current meters will show up two tube's reading
    07: If tube reading is same.That's perfect. If reading is different. Should be no more than 2 or 3 mA difference for a good balance between the tube
