Product Description
-
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
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
