SV-300B MKII
Push-Pull-Ended Monaural Power Amplifier

  • All of the transformers are specially manufactured by Tamura Corp.
  • Since these transformers (except for the interstage) come with lead wires, it's easy to assemble.
  • A hard-wired is used for all of the circuit. (which means no Circuit Board.)
