All of the transformers (Power, Choke and Output) are specially manufactured by Tamura Corp.

For better sounding, there is no Printed Circuit Board in the circuit. (A hard-wired is used for all of the circuit, though it makes a complicated wiring and requires the technical skill to assemble.)

Due to above reason, this model is factory assembled version only.
