Description

Product Description 01: Global voltage standard ( 100V~240V ) 02: 9pin probes cable lengh: 55cm 03: T2 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes) 04: T2 can test many types. At present, we have 8pin and 9pin probes options 05: This listing T2 suitable for EL84 6BQ5 6P14 etc. 06: T2 can get the reading direct from the current meter. It does not need any convert from mV to mA. 07: T2 use LED Amp Meter Ammeter Current Panel,Better performance than LCD. What's in package? 1pcs T2 Tester Body 2pcs 9pin Bias Current Probes 1pcs AC/DC Adapter ( 100V~240V ) 1pcs USB Connecting Line Note: Keep the amplifier silent during use T2, 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 T2 tester probes socket. 03: Then plug T2 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 up and down. Get two 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
