AKAI Hi-Fi System in excellent condition bought from new in 1970s (made in Japan)Cassette / Reel to Reel / Radio and Speaker System in Four Boxes (all cms) 40 x 50 x 40 reel to reel 40 x 50 x 30 radio71 x 50 x 38 each speaker (2 boxes) AKAI Stereo Receiver AA-8080AKAI 5 Way 6 Speaker System SW-175 in original boxes (2 Speakers)AKAI Tape & Reel to Reel Player GX-1900D with Front Panel Cover DESCRIPTIONThis was a combination reel to reel/cassette stereo recorder available as either a self-contained unit with internal amps and monitor speaker (GX-1900) or as a deck only (GX-1900D). Two-way transfer was achievable, either from cassette to reel or visa versa. A single hysteresis synchronous 2-speed motor was employed, coupled to a jumbo flywheel maximized tape speed accuracy and minimized wow and flutter. GX heads were used in the cassette recorder but not in the reel to reel section.A low-noise, silicon transistor record and playback equalizer amplifier ensured optimum eq at both tape speeds and tape lifters were employed on the reel unit during fast wind. Other features included automatic stop and shut-off, large illuminated VU meters and the standard Akai pause/start button coupled to the twin-lever transport controls. The cassette unit utilized push-tab buttons.ADDITIONAL INFOFrequency response (3dB)30Hz – 22k Hz 7½ ips30Hz – 15kHz 3¾ ips40Hz – 15kHz 1 7/8 ips (cassette)Wow & flutterReel to reel: 0.12% at 7½, 0.15% at 3¾Cassette: less than 0.2% at 17/8 ipsTotal harmonic distortion: 2%/ Distortion: less than 2% (1,000 Hz “0” VU) / Crosstalk: 45dB / Erase ratio: better than 70 dB / Hum and noise: less than 10mV at minimum tone control / Crosstalk: better than 45 dB (stereo), 60dB (mono) / Semi-conductors: 16 transistors, 12 diodes, 2 linear IC’s & 2 power IC’s (GX 1900 only) / Audio output power: 10 watts per channel / Inputs: Microphone: 0.5 mV impedance 5 Kohms Line: 50 mV impedance 200 Kohm DIN: 0.4V / 50 mV (High) 3 Mv (Low) / Outputs: Line: 1.228V (+4 dB using a 25Hz test tone “0” VU) Headphones: 30 mV at 8 ohms Speaker outputs: 10 watts / channel at 8 ohms (GX-1900 only) / Speaker(s): 2 built-in 4? speakers (GX-1900 only) Four Boxes
