Amptata T1 Valve Checker Bias Current Tester Tube mA Match Tool 7591 7591A

Description

Product Description
01: Global voltage standard ( 100V~240V )
02: Octal 8pin probes cable lengh: 55cm
03: T1 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
04: T1 can test many types. At present, we have 8pin and 9pin probes options
05: This listing T1 suitable for 7591 7591A etc.
06: T1 can get the reading direct from the current meter. It does not need any convert from mV to mA.
07: 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
