Description:
V-Fet is the acronym for the newly developed vertical type field effect power transistors used in the TA-4650 amplifier.
A V-Fet has extremely low output impedance and excellent high power capability, delivering an output current proportional to input voltages and assuring virtually distortion free amplification.
Use of the V-Fets in the power output stage results in a quality of reproduction hitherto not available to audiophiles.
