Background of V-FET : V-FETs are the best solid state power device in the audio history. They were invented in Japan specifically for audio application. V-FET is renowned for its tube-like triode characteristics. 2SJ18 and the complementary 2SK60 are used in SONY's TA series amplifiers in the 70-80's. That was the climax of solid state amplifiers.
The listing is for one piece. Good for your hi-end audio amplifier projects looking for V-FET or SIT. Also good for repair of vintage Sony or Yamaha and NEC amplifiers.
For this listing, all the 2SJ18 were tested for Vgs. The Vgs is labelled on the case of the component.
Testing condition : Vds = 20V. Vgs taken at Id ~10mA.
We left 5 pieces with Vgs of 6V+/- 0.5V.
