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

A hard-wired is mainly used for the circuit. In addition, Printed Circuit Board is used in a little part (amplification section) only.

This model has a design matching with SV-amplifiers except for SV-300BSM because of mostly same Width and Depth. (which can be used with SV-amplifier setting it on the top panel.)
