• Brand Model : Amptata V8
  
• Global voltage standard ( 100V~240V )
• 9pin probes cable lengh: 55cm
• V8 tester is all metal fuselage. A separate resin board is used at the top. Prevent short circuits making readings incorrect
• V8 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
• V8 can test many types. At present, we have 8pin and 9pin probes options
• This listing V8 suitable for EL84 6BQ5 6P14 etc.
• V8 can get the reading direct from the current meter. It does not need any convert from mV to mA
• V8 use LED Amp Meter Ammeter Current Panel,Better performance than LCD

What's in package?

• 1pcs V8 Tester Body
• 4pcs 9pin Bias Current Probes
• 1pcs AC/DC Adapter ( 100V~240V )
• 1pcs USB Connecting Line 

How to use it? 

• 01: Turn off amplifier.
• 02: Remove the tubes then plug in V8 tester probes socket
• 03: Then plug V8 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
