All seems good.  Tacky old lube all over.  Dirty switches etc.  All the usual suspects



What a nice and solid mechanism.  Nicely balanced with perfect matching springs to give it a solid feel.

Going in on the other side



Cleaning as we go



Unit is reassembled.  This is an awesome machine.  It gets some amazing base from a cassette.  Yet crisp on the highs.  This is still old tech.  So for what it is, it sounds good.  Love old school :groovy:

Back on the Akai again.  Replacing the 20 x snubber components.  Mantech said they can get, but never came back with price or availibility.
The relay board and the control board contains 20 in total. 120 ohm 1W resistor in series with 0.1uF poly cap 400v.  I will grab a pic shortly and share.

This is the control board.  Pic is not great, but the orange squares left middle are swollen and cracked.

On the Akai 4000D. The cam for the FFW and RWD gave in. The pic shows the original cam RH and home made cam LH.  The original is held together by Q Bond.  Took about 6 hours with a hacksaw and files.  Not pretty, but 100% Functional.


And here it is in position.
