Single-Ended Stereo Power Amplifier

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

this specifications are subject to change without notice.

KT88 tubes are operated in Ultra Linear mode.

*1 Since the output transformer has two wires (one for 8ohm, another one for 16ohm) in Secondary, you can change the value with re-wiring from the transformers to the speaker terminals by yourself later. (NOTE: there is only one pair of speaker terminals per channel on the chassis.)
*2 Now, we deliver all of our SV-amplifiers except SV-300BSM with exchanging among three kind of power transformers just like below in order to be used for all over the world.
1) 100V version
2) 120V version
3) 220-240V version
