How to use it ?
1. Turn off your amplifier, and connect two probe testers separately to the A and B interface of CT1-BOX.
2. Remove the power tubes, insert them into the bias probe sockets.
3. Insert bias meter probes into the tube sockets of the amplifier.
4. Turn on your power amp, let the tubes get warm about 5 minutes, then read the bias measurement.
5. The left current meter is reading "A" input, and the right current meter is reading for "B" input. If the reading value of both are the same, that's perfect. If not , the difference should be no more than 2mA or 3mA for a good balance between the tubes.
