Nowadays such devices are rare, some audiophiles put this Nakamichi in their home audio system. The head unit is extremely sensitive to improper installation in the car, I want to list the main mistakes. The head unit itself when installed in the panel can rest against some obstacle (wiring harness, block of some device, fasteners).Inexperienced installers will try to force the missing distance to fix the head unit flush with the panel. In the back at this moment the MB-100 housing wall will bend and kill the CD changer mechanism... Instead of enjoying the music, the customer gets an expensive repair.
The most trivial error, do not feed the minus wire. More precisely not in time, in the last turn. They connect the interblock wires to external amplifiers, and then, by mistake, first connect the PLUS from the battery.Processor unit burns out immediately, the minus is not connected yet! Be sure to take this point into account when connecting. At the beginning of the work it is necessary to disconnect the car battery, and only then start the installation. First the power wiring, then the connection cables to the amplifiers. The Nakamichi mechanism is extremely sensitive and precise.
The gaps between the moving parts are counted in fractions of a millimeter. During installation there can also be a slight tilt in the case, "twisting", when the screws are tightened into the case unevenly or with different force.
This is not noticeable, but the parts of the mechanism begin to cling to each other and to the walls of the case. Time passes, and the radio unit refuses to work.On the display an Error ("E-MECHA") is displayed. I disassembled several of these mechanisms Nakamichi, you could see dirt on the edges of the disk guides. The owners were putting discs with dirt that had been stored in the car in poor conditions, taking the discs with their hands greasy from food, and so on. In inconspicuous amounts, dirt accumulates in the mechanism, and jams, misalignments, and the result is a constant "E-MECHA".. So pay attention to the proper installation of such equipment! In the transport position the mechanism of the radio is fixed with two bolts and a pin!
The reason is clear - the mechanism was not fixed! Keep in mind this nuance. The most frequent and brand-name failure of such Nakamichi changers is breakage of a magnetized round washer.This stays on the disc while it is playing, and is removed by a mechanical "hand" when playback is finished, the disc is changed, or the disc is turned off. It is taken out, put back, and if the mechanism is not broken, the transport will work again until the problem recurs. That's why the service repair manual advises to replace this part with a new one. The new magnetic washer is exactly the same, but with a felt lining, to reduce the effect of magnetizing force Some masters simply glue a circle of similar material to the bottom of the washer.
The head unit is new, sealed, I haven't opened them yet. Free of charge, of course. By video link or by a series of pictures I will show this interesting process for you! And you will get the finalized device. I wish everyone good luck and success!The item "Top quality car stereo Nakamichi MB-100. One of the last in the world" is in sale since Sunday, March 14, 2021.
