Product Description
  • Brand Model : Amptata T1
  • Global voltage standard ( 100V~240V )
  • Octal 8pin probes cable lengh: 55cm
  • T1 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
  • T1 can test many types. At present, we have 8pin and 9pin probes options
  • This listing T1 suitable for 7591 7591A etc.
  • T1 can get the reading direct from the current meter. It does not need any convert from mV to mA.
  • T1 use LED Amp Meter Ammeter Current Panel,Better performance than LCD.
What's in package?
  • 1pcs T1 Tester Body
  • 4pcs Octal 8pin Bias Current Probes
  • 1pcs AC/DC Adapter ( 100V~240V )
  • 1pcs USB Connecting Line 
Note:
  • Keep the amplifier silent during use T1, 
  • 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 T1 tester probes socket.
  • 03: Then plug T1 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: Switch from A to B to C to D. Get four 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
