Octal 8pin probes cable lengh: 55cm
T4 tester can measures the cathode current of the power tube for bias reading (at low voltage side of the tubes)
T4 can test many types. At present, we have 8pin and 9pin probes options
This listing T4 suitable for EL34 KT88 6L6 6V6 5881 6550 KT66 KT100 KT120 7027 etc.
T4 can get the reading direct from the pointer-type current meter. It does not need any convert from mV to mA
What's in package?

Keep the amplifier silent during use T4
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 T4 tester probes socket
03: Then plug T4 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: Two pointer-type current meters will show up two tube's 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
