The Sony TA-4650 Integrated V-FET Amplifier is a powerhouse of audio delivery, boasting an output of approximately 60 watts per channel. Its standout feature lies in the employment of V-FET (Vertical Field Effect Transistor) technology, offering a unique sonic signature with excellent clarity and power handling. Equipped with various inputs and tone controls, it allows users to tailor the sound to their preferences while maintaining fidelity.
Accompanying the amplifier is the Sony ST-4950 FM/AM Tuner, a precision-tuned component ensuring accurate reception across radio frequencies. Its design focuses on delivering clear and crisp radio signals, supported by its user-friendly interface and stable tuning mechanisms. The tuner pairs seamlessly with the amplifier, providing a diverse listening experience with access to numerous radio stations.
Completing this vintage audio setup is the Sony TC-209D Cassette Deck, a versatile unit offering both recording and playback functionalities. Boasting reliability and quality, this cassette deck enables users to record their favorite music or listen to prerecorded tapes with fidelity. Its intuitive controls and playback mechanisms contribute to a comprehensive audio system, allowing users to enjoy music from various sources with exceptional sound reproduction.
Together, these components from Sony represent an era of audio excellence, showcasing the brand's commitment to delivering high-quality sound and reliable performance. The integrated amplifier's power, the tuner's precision, and the cassette deck's versatility combine to offer a complete audio experience, reflecting the pinnacle of Sony's craftsmanship and engineering in vintage audio equipment.
The entire set is in good condition. All have been tested and work perfect. Some usage marks across but very normal given the age of all components. Looks very good, all lightning works exept for the power light on the amplifier
