Commentary
This tube type pre-main amplifier is ideal for high-grade Walkman and mini components.
The vacuum tube uses 12AX7 for the first stage and KT88 for the output stage.
The first stage is a direct-coupled circuit, and the feeding to KT88 uses a cathode follower circuit with low impedance and features.
KT88 uses a fixed bias circuit with variable bias voltage to control the amount of current. This enables the use of other vacuum tubes such as EL34 and 6L6GC.
All transformers are originally designed by Triode and are manufactured and adopted in China.
A glass epoxy substrate is used for the substrate.
It has an input volume.
The kit is designed so that even people who have never made amplifiers can make it easily.
The wires are cut to length according to the place of use, and other parts including screws are sorted in small numbered bags.
In addition, there were repairs for malfunctions at the completion of the kit and the completion inspection guarantee system at the completion of the kit.
