Description: Item TitleDescription**YAMAHA CR-400 - ¥59,000 (circa 1974)** **Description** The CR-400 is a stereo receiver designed with a focus on high sensitivity and cost performance. The main amplifier section utilizes a fully direct-coupled pure complementary OCL (Output Capacitor-Less) circuit. Additionally, the first stage differential amplifier employs FETs as a constant current source, allowing for ample negative feedback and achieving high stability. The main amplifier circuit also functions as an active subsonic filter, cutting off frequencies below 20Hz (3dB down point) at a slope of 12dB/octave. For the equalizer amplifier, a monolithic IC with a three-stage direct-coupled circuit is used, ensuring high stability, low distortion, and high gain. The use of high-quality components in the equalizer elements further enhances performance. The tone control circuit features Yamaha's unique NF (Negative Feedback) type, which applies feedback between the collector and emitter of a two-stage direct-coupled amplifier, resulting in straightforward control characteristics and low distortion. The microphone mixing circuit includes a dedicated three-transistor amplifier that operates independently of other program sources. By utilizing the Pre out terminals, mixed signals can also be recorded onto tape. The FM tuner section incorporates low-noise FETs, a three-gang variable capacitor at the front end, and differential amplifier ICs with excellent limiter characteristics, along with ceramic filters and dedicated ICs in the MPX circuit, achieving high sensitivity and selectivity. The AM tuner section features a circuit design that emphasizes sound quality, minimizing interference from adjacent stations and delivering distortion-free AM reception. The device employs a dual meter system for signal strength and tuning.Shipping Send by FEDEX International Buyers - Please Note:Import duties, taxes, and charges are not included in the item price or shipping cost.
