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

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
