Description
Nakamichi IA 3 2nd of two see other items. Fully serviced to factory spec. Please study the pictures for more detail. Idle current is set as per the service manual 7mv, Nichicon capacitors measure to spec with very low esr, Alps potentiometer and switching. The amplifier circuits are 100% discrete - no ICs are used. All parts are of the finest quality. Voltage amplification is performed by a differential two-stage circuit. The IA-3 power amplifier section is rated at 40 watts per channel (stereo) into 8 ohms. The oversized power supply and high-current output stage, however, result in considerable dynamic headroom, enabling the clear reproduction of demanding musical peaks. The amplifier low-impedance drive capability is exceptional. Efficient dissipation of thermal energy is assured by heat sinks made of black almite. Starting at the inputs, separate ground lines are maintained for the left and right channels, becoming common only at the speaker outputs. This through left/right ground isolation is especially important in the low-level stages and contributes to greatly enhanced stereo separation and imaging. The Essential Features: In the interest of musical resolution and sonic transparency only an input selector, a record output selector, a volume control, and a power switch are provided. Inputs are available for Tape, CD, Tuner and Aux. The amplifier circuits are 100% discrete - no ICs are used. All parts are of the finest quality.
