Pre Amp SVC-500.

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.

Power AMP Mono : SV-300BSM

Ultra big size transformers are used for both Output and Power supply.

Double choke transformers are used with Triple metallized polypropylene

capacitors for the plate voltages.

All of the transformers are specially manufactured by Tamura Corp.

A hard-wired is used for all of the circuit. (which means no Circuit Board.)
