Stereo Integrated Amplifier
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.
Power output: 30 watts per channel into 8Ω (stereo)
Frequency response: 10Hz to 100kHz
Total harmonic distortion: 0.05%
Damping factor: 45
Input sensitivity: 2.5mV (MM), 150mV (line)
Signal to noise ratio: 70dB (MM), 90dB (line)
Output: 150mV (line), 17mV (DIN), 1V (Pre out)
Speaker load impedance: 4Ω (minimum)
Semiconductors: 6 x VFET, 4 x FET, 36 x transistors, 26 x diodes
Dimensions: 460 x 168 x 323mm

Love my old Sony VFET TA 4650. Bought it in 1980, still using it in my primary system.

Typical SONY quality and innovation from that era, for VFETs, very reliable and cold, amplifier driving my modern high-end speakers and sounds fantastic with external PRE-AMP. Sound is very detailed, warm, slow without technical transistors sound even with class A
