AKAI X-201D Reel to Reel Tape Recorder (1973-77') - Test after repair and maintenance

Akai X-201D - Stereo 4-track Reel to Reel Tape Recorder repair & maintenance in Baltic States - https://t.me/Master_Man_Service in Riga, Latvia (EU) Description: On conventional recorders, the signal and bias are applied to the same recording head. Therefore, the frequencies recorded, especially high frequency signals, tend to be attenuated or erased by the effect of the bias field. With the exclusive Akai Cross-Field Head, however, the signal and bias heads are mounted separately in opposition with each other with their centrers slightly off. As the recorded signal is entirely unaffected by the prevailing effect of the bias field, tape can be recorded over the entire frequency spectrum with maximum fidelity even at low tape speed. Specifications: Track system: 4-track, 2-channel, stereo/monaural system Heads: 1 x record/playback, 1 x erase, 1 x bias Motor: 2 x reel drive, 1 x capstan Reel size: up to 7 inch reel Tape speeds: 1 7⁄8 3 3⁄4 7 1⁄2 ips Wow and flutter: 0.08% (7 1⁄2 ips) Frequency response: 30Hz to 26kHz (7 1⁄2 ips) Signal to Noise Ratio: 50dB Total harmonic distortion: 3% Crosstalk: 45dB Input: 50mV (line), 5mV (DIN), 0.5mV (mic) Output: 1.23V (line), 0.4V (DIN) Semiconductors: 16 x transistors, 17 x diodes Dimensions: 358 x 358 x 227mm Weight: 17kg https://www.hifiengine.com/manual_lib...
