These two units supply all the power needed for the PCB components (sound system, LEDs, touch controller etc).
My photos will look a little different at the bottom as we had to jerry rig an extension cable to feed power into the unit since I don't have the original cabling for it. Works fine on American power, theoretically works fine in europe without a transformer as well based on some reports. R1 uses a 300VA step down transformer https://cdn.discordapp.com/attachments/267603668046446603/1045057845999173692/IMG_20221123_112537805_HDR.jpg but that's probably overkill.

The most interesting part of the PCB. Custom part made by Pentel. Two of these exist on the PCB board that process 6 channels each, to get the 2 halves of the touch controller. Each segment of the touch controller has one of these as well, with the addition of the ribbon cable to connect the segments together.

The existence of this board is a bit overkill for what it's used for, likely it *had* to be used due to Sega producing the cabinets for Marvelous. This is a newer version of the control board that has a USB port on it, almost all sega cabs use this now. Note: Wacca does NOT check for a coin counter, so the resistor trick is not needed to apply credits in game.

## Touch Controller
-There are 12 of these bad boys divided into two halves, set to channel 1-6 on each side that feed back into 2 touch unit control boards. Each one weighs x grams which totals to about 40 LBS. Somehow I never really understood how MASSIVE these units are until I held an individual segment in my hand.

Somehow I never really understood how MASSIVE these units are until I held an individual segment in my hand. 5 LED segments per unit, with 4 segments across the acrylic making 240 "keys".
Here are some scans of a segment that shows the curve profile.

## Replacement LED PCBs
Wacca LEDs are notorious for being burnt out, you've likely received your machine in a state where some panels are not getting color data, are dim, or are straight up not lit up. This is partly due to the design of WS2812.
