Amplifier 7591 7591A Vacuum Tube Tester V8 Bias Current Checker Octal mA Version

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 7591 7591A 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 Octal 8pin 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 On Sep 23, 2022 at 03:53:26 PDT, seller added the following information:
