So I have finally started my switcher upgrade in my Pole Position. I do not like the reputation of the old linear supplies in this game, so I searched and found the following link.

Following these instructions, I first began to modify the AR boards for operation on 12v from the switcher. In doing this modification, the 5v output from the AR board will be disabled. Thus, the 2 AR boards will only be audio boards from here out.
Note that R29 is burnt, but will be jumpered out in this process.
R30 will also be jumpered out.
2N3055 will be removed
2N3055 removed. Do NOT reinstall both screws as one will short out the board.
I installed jumpers under the board to make this easily reversible.
I will post additional pictures as I progress.
