Description

Product Description
Brand Model : Amptata T3
Global voltage standard ( 100V~240V )
Octal 8pin probes cable lengh: 55cm
T3 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
T3 test tool is through multimeter get tube's mA
It does not need any convert from mV to mA
T3 can be work with all kinds of multi meter (Digital meter or analog pointer meters) ,at range of 100mA or above
T3 can test many types. At present,We have 8pin and 9pin probes options
This listing T3 suitable for 7591 7591A etc.

02: Turn off speaker sound,Do not turn on sound play songs
03: Insertamplifier just is let the tube get power and warm up
04: Read most accurate's tube cathode current in working state
How to use:
01: Set multimeter to the mA range (most common is 200mA)
02: T3 Black banana plug into COM jack of multimeter
03: T3 Red banana plug into mA jack of multimeter

08: Read the bias measurement
09: Switch from A to B to C to D,Get four reading
10: 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
