[A6] Endcap replacement instructions

[Geoff Moehrke]

1. Open the unit and remove panel PCB

Remove the top panel so you can see which knobs need to come off...
Which involves all of the screws along the
rear at the division of the top and bottom panel, as well as the four
screws direcly under the pitch and mod wheels
and the screws along the left and right edges, and the screws directly
under the length of the ribbon controller.
The ribbon controller screws are a bitch to replace; you have to have an
awl or small screwdriver inserted into one
or more of the holes to guide the ribbon controller metal back to
alignment before inserting and tightening those screws.

Note that once you have the top unscrewed, set the unit back down on
it's base and slowly lift the top up by the endcaps, working it around
anything that catches. ONLY lift it straight up, as if the top of the
unit were levitating. If you tilt it, you will break the endcaps. Once
you've lifted it a few inches, having worked around the bits that
"catch", you can then tilt it, opening the unit like a clam. Note that
there are ribbons connecting the base to the top so keep them close
together.

If the top won't come up easily, you can flex the endcaps out at the
very bottom a bit to help.

2. Remove all screws which mount this PCB to the front panel
3. Remove the PCB from the front panel to gain access to the endcap
mounting screws
4. Unscrew and replace the endcap

There is a metal bracket which mounts on the endcap plastic that has to
be swapped onto the new part, and then you screw it to the FP metal.

5. Replace front panel PCB making sure all buttons are correctly
centered in the FP holes and none are held down inadvertantly.

Especially before tightening any screws down all the way!!!! Mount the
PCB and start a few screws at the corners in order to hold it there, and
press it onto the front panel, and make sure that the buttons are all
clear. Then tighten those screws some more, and check all of the buttons
again. Press them if need be to insure that they are "free". As you do
this, add more screws. Don't do them all though; when you get about
halfway through, do the following:

6. power up unit and run button self-test to check operation of all
buttons

I believe that it is soft button 2 to run the self-test. Note that
you'll need the sustain pedal for each jack test, and a midi cord run
from in to out for the MIDI test. Turn each pot through their entire
throw, press each button, run up and down the ribbon and wheels, etc.

7. reassemble unit

Then power it up and if you want to be certain that all is well, run the
front panel test again.
