Akai GX-230D


The new Akai AC servo motor employed in the GX-230D for direct capstan drive is equipped with 114 gears on bot the rotor and stator sides and a detector coil and magnet are built in on the stator side for a completely new pulse detection system.

With this system, pulse detection is made only once every 114 pulses instead of at each pulse for greatly increased pulse output.

Other advantages of this system over the usual DC servo motor with magnetic braking system include simplified construction, absence of heat generation, and substantially decreased ripple as a result of the mechanical eccentricity of the motor.

One each, GX forward/reverse playback and combination record/erase head guarantees long lasting performance, wider dynamic range and excellent signal to noise ratio.

Model GX-230 is also available and incorporates the same outstanding features as the GX-230D, but is equipped with a speaker jack for playback.

re: GX-230D

hello community,

I am fiddling with my grandpa's old Akai GX-230D. I know nothing about this machine other than some quick research online. I have the tape all threaded thru and it's moving along fine. The problem is the sound. I read through the owners' manual and couldn't come to a conclusion if external speakers are necessary to hear the sound or if they aren't needed. Since this is the 230D model there is no specific speaker jack. So I'm assuming I would need to connect it to the "Output" right and left jacks. Any help would be greatly appreciated.

re: GX-230D

Yes, D mean deck - no power amplifier ! You must connect that to the stereo amplifier through output jacks. Otherwise headphones are OK too.
