It requires no less than the removal of 26 screws, the faceplate, the Jack Board, three wire harnesses and three mounting plates. Broken traces on the Switch Board are a common point of failure with the S‑550, S‑220 & MKS‑100.
Over time, moving the sampler around will place too much strain on a particular section of the Switch Board and it will eventually crack.
Do yourself a favor and buy a couple of spares because... IMG Note: If you have a hard disk drive and/or CD‑ROM connected to your S‑550 and you use the HD5‑IF or CD‑5 floppy disk to boot your sampler, use that *. OUT File (I have included both of these disk image files in the large *.
shit happens When I replaced the tact switches on my W‑30, the position of the Panel Board was slightly lower than expected. ZIP file mentioned above) simultaneously until the LED display reads b0.0.
The problem area is located near the If your S‑550 is experiencing distorted sound output, it's possible the previous owner was careless and connected one or more of the 1/4" output jacks to a non‑grounded mixer or some other type of non‑grounded equipment.
Since the S‑550 is not grounded by default, this can easily damage one or more of the nine output transistors on the Analog Boar.

Right before you turn off the sampler and call it a day, load the System Boot Disk Image file 000. This way, the next time you power on the sampler, the operating system will boot automatically and you will be ready to rock Get into the habit of always removing the flash drive right after the sampler counts down from 80 to 0 after each disk load or disk save procedure.
