Description

Product Description
Brand Model : Amptata V8
Global voltage standard ( 100V~240V )
Octal 8pin 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 EL34 KT88 6L6 6V6 5881 6550 KT66 KT100 KT120 7027 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

1pcs AC/DC Adapter ( 100V~240V )
1pcs USB Connecting Line
Note:
Keep the amplifier silent during use V8
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 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
