     Phono TRIX 88.    Portable reel-to-reel tape recorder. It is also called a pocket, but a pocket for him to be very large. They produce in Germany since 1961, and were an alternative to more expensive recorder Minifon. In the U.S., the recorder Phono TRIX 88 sold for just $ 139.95. Dimensions of the recorder - 197 x 106 x 48 mm. Weight without battery 1.14 kg. Feeding motor 4,5 v, three-cell battery C. Power electricians 4,5 v, three-cell battery AA. In the recorder used the coil diameter of 66 mm tape width 1/4 inch. The speed of the tape is stabilized, and is 1, 7/8 inches per second. On the coil (420 foot tape) you can do up to 70 minutes of recording time (2 x 35 min.). It was such a coil is $ 2.50. Circuit collected by 6 transistors. In the universal amplifier, which includes the bias generator uses five transistors, OC74, or OC75 (2 pcs.), TF65 (3 pcs.), And one OC74 (OC75) is used in the stabilizer motor speed. Overall impression of the voice recorder is good, but call it a laptop or pocket may be only conditionally. If Minifon really can be hidden under his jacket, then Phono TRIX 88 can be hidden just under his coat. For other parameters recorder is good, made by German quality and technologically, and construction of all units are well thought out. Circuit consists of two boards. Fee stabilizer speed of the motor is located under the battery cover, and the amplifier board on the kinematics, when viewed from below. It connects to the wired recorder with two planar five-pin connectors. Connectors accessories are located on both sides of the control buttons, and a different color. Input connector is red, the output - blue. Connector for external power supply is located near the battery compartment. Also there are two switches. One of these switches work on batteries or from an external adapter. Second, next to the volume control, includes a mode Remote start recording, and pause during playback. To switch between recording modes - play are two dependent buttons with color inserts. Pressing the blue - reproduction, red - the record. During recording, the sound is transmitted to the headset. The quality of the recorder, normal, approximately the same as in Minifon Attache, but unlike the latter, there is no fast forward.    
     The device was bought in working condition. It took only cleaning and lubrication of kinematics. In the kit there is an original dynamic microphone with the switch of modes microphone - speaker. That is, the microphone can also be used as a speaker. Also this switch serves for remote control when recording.
     Also add that the exact same voice recorders were produced under the name Felaphon TG 99.
