Vintage Akai X-150D Reel to Reel Tape Recorder Deck VG SN 34378. In very good shape. All major functions work. Counter doesn’t move. I used a signal into mic inputs to test the record function to a blank tape. Right VU meter moves less than the left, play back and record are weaker on the right channel. My blank and recorded tapes are old and not in the best shape, your tapes might work better. This deck could use a service. Not everything was fully tested. A copy of the user and service manuals on CD is included. No tapes or reels included. Please see all the pictures for more details. Description from the net. The cross-field head created a sensation in the tape recorder market by making possible a wide range recording never before heard on any conventional tape recorder. Using this cross-field head, Akai model X-150D provides a surprising recording performance of 30-23,000 cps at a tape speed of 7-1/2 ips, 30-18,000 cps at 3-3/4 ips and 30 to 9,000 cps at 1-7/8 ips. What is superior about cross-field recording? How does it differ from typical recording methods as far as construction is concerned? In the typical recording system, the signal current and the bias current are combined together and applied to the recording head. It is well known that the purpose of bias current is to record, at high sensitivity, a signal applied on the tape, with little distortion and minimizing noise generation. However, the bias current providing such an advantage also has an undesirable character. That is, the wide magnetic field of the bias current affects the recorded signal, resulting in weakening or even erasing the signal. This phenomenon is particularly noticeable at high frequencies. In the cross-field system, the signal current is applied to the recording head while the bias current is applied to the bias head. These two heads are located in different positions, as determined inter-relatively, so that the magnetic field of the bias will not affect the signal recorded on the tape, even when sufficient bias is applied. This allows the recorded signal to remain on the tape with high fidelity. Track system: 4-track, 2-channel, stereo/monaural system. Heads: 1 x record/playback, 1 x erase, 1 x bias. Motor: 2 speed hysteresis synchronous. Tape speeds: 1 78 3 34 7 12 ips. Wow and flutter: 0.12% (7 12 ips). Frequency response: 30Hz to 23kHz (7 12 ips). Signal to Noise Ratio: 50dB. Input: 60mV (line), 0.5mV (DIN). Output: 1.23V (line). Semiconductors: 11 x silicon transistors, 2 x diodes, 2 x rectifiers. Dimensions: 340 x 340 x 230mm.
