The AK25 uses the rear stacking mech rather than the 5 tray nightmare. You
know, the one with the 5 flying saucers in the back, and a single tray that
takes discs in, and then passes them back to the stacker ?? That mech is
very straightforward to align, requiring only that the reason for the jam,
if any is resolved, followed by withdrawing the tray by hand, using the free
gear wheel moulded into the top of the mech if necessary. When the tray
reaches its stops, the latch at either side needs to be pushed out, and the
tray withdrawn further until it comes right out. The basic mech operation is
then checked by using the gear wheel fixed on the end of a jeweller's
screwdriver, and finally wound until the deck is down, and the gear at the
side is turning in the direction to drive the tray out. You then have to
make sure that the sliding tray is correctly located and locked in the
drawer, then that the white rack under the right side of the tray, is pushed
as far away from yourself towards the back of the tray as possible, and then
held there with the index finger of your right hand. The tray should then be
offered into the locating grooves either side, and slid forward until it
touches the drive gear. Then, making sure that you keep the white rack
pushed fully forward ( very important, DONT LET IT MOVE ), push the tray in
until it clicks past the latches, after which the rack will start to move
back, and that's it. Confirm that all is ok, by winding the mech using the
free gear tool that you have made up. If it sticks with the tray fully back
in, then goes with a loud crack, don't worry, it just means that you let the
rack move as you pushed it in. Just take the tray back out, and do it again.
It really is a lot easier to do than describe. Very occasionally, you will
find that something on the sliding white rack section is damaged, causing
the initial problem, but it's pretty rare, if the mech hasn't been abused.
On the nightmare mech, my son has become pretty adept at these now, and can
do one in about 10 minutes. He recently filmed one, with sound, in its test
cycle, which he now uses as a screensaver. It's fascinating to watch. Quite
mesmerising in fact. When it's working right, it really is a very elegant
piece of engineering. If you want a copy, or anyone else, mail me off-group
and I'll send it to you.
