Akai Cd 93

tuncay · 16th October 2006, 10:24 AM

My AKAI CD 93 cd player needs an M50747-433SP. This is an ic produced by Mitsubishi for Akai CD93 and CD73 model cd players.

As it is a microprocessor declared "obsolete" you will have a hard to time to find one. I think a realistic option is a obtaining a second ( defective ) CD73/93.

You could try to mail various Akai companies in Europe for a start.

I have sent inquiries to a number of Akai dealer or services in Europe, but honestly I have received nothing in response. As for second hand ones, it is hard to find second hand firms which are in Europe.

A second hand one in Turkey ( Istanbul ) perhaps ?

Thank you for your mails. Do you think we could get a second hand in europe? Actually, my player is in a great condition, except for that part. so, once got a cd93 or cd73 cd player in any condition We could sort out the problem..

I think AKAI CD 73 model players have got the same system, thus the part M50747-433SP as the microprocessor unit in them, as well..

Hello!
I have tracking problem with akai CD73.
There are linear tracking motor with two coils.
Motor and sensor coil.
Sensor coil was broken.
Sensor coils electrical resistivity is now about 10 kiloohm.
Too high I think.(In denon this is about 2 kiloohm)
Player cant perform track jump function.
But from beginning plays well.
Can eny body help with right resistivity.
