Product Description Brand Model : Amptata T3 Global voltage standard ( 100V~240V ) 9pin probes cable lengh: 55cm T3 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes) T3 test tool is through multimeter get tube's mA It does not need any convert from mV to mA T3 can be work with all kinds of multi meter (Digital meter or analog pointer meters) , at range of 100mA or above T3 can test many types. At present, we have 8pin and 9pin probes options This listing V8 suitable for EL84 6BQ5 6P14 etc. High-Quality 24K Gold Plated Banana Plug Male Speaker Cable Connectors Bakelite socket and gold pins for long life,Tough gold pins with a thick gold plating Package Contents 1pcs T3 Tester Body 4pcs 9pin Bias Current Probes Note: 01: Keep the amplifier silent during use T3 02: Turn off speaker sound,Do not turn on sound play songs 03: Insertamplifier just is let the tube get power and warm up 04: Read most accurate's tube cathode current in working state How to use: 01: Set multimeter to the mA range (most common is 200mA) 02: T3 Black banana plug into COM jack of multimeter 03: T3 Red banana plug into mA jack of multimeter 04: Turn off amplifier 05: Remove the tubes then plug in T3 socket 06: Then plug T3 in amplifier socket 07: 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 08: Read the bias measurement 09: Switch from A to B to C to D. Get four reading 10: 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
