TRK-3488 is designed as a tribute for the 15 anniversary of the founding Triode Corporation Japan.
We look forward to making a return to the basic values of the triode TRK series as originally debuted. The concept is a Class A design and can use either EL34 or KT88 to enjoy the splendid sounds. Using one or two tubes, this amp automatically adjusts its bias system.
The contents of this kit is complete. Just solder the components to the printed circuit board, install the chassis wiring board and youĺre almost done. Tip - Take time to install the wiring and volume control around the input plug. Average time of creation is 5-6 hours.
Kiwame resistor or Vcap upgrade is available.
