Some old instructions of mine regarding upgrading the original Arachnid power supply to a switcher:
Converting a 6000 (Super Six), 6100 (Super Six Plus), 6200 & 6300 (Super Six Plus 2) power supply from that crappy linear design to a modern switching regulator. You will need a screw terminal switching regulator power supply capable of outputing at least 3 amps (preferably 4 amps) on the +12 volt line. The reason for this is that the monitor, amplifier, and coin door lamps/gameboard lamps/pushbutton lamps all run on the 12 volts.
1. Remove the old circuit board that's screwed to the big blue capacitor.
2. Remove the big blue electrolytic capacitor and it's mounting bracket.
3. Remove the power transformer. Follow it's black wires underneath the chassis to the lamp dimmer circuit board. Now cut off the black wires an inch or two away from the board.
4. Butt splice an 18 gauge stranded wire to each of the black wires you just cut on that board. The wires should be about a foot long for each one. These will be the AC power wires to the new switching regulator power supply.
5. Place the new switching power supply on top of the chassis and mark locations of it's mounting brackets and drill four 3/32" holes. When drilling the holes be sure not to drill through the lamp dimmer board (or it's components) and make sure no metal filings/shavings fall on the board. Mount the new supply with four #6 sheet metal screws about 1/4" to 3/8" long.
6. Now to connect the DC outputs of the new supply to the game harness Connector J1 which plugged into the original power supply. Connect all the +5 volt wires of the game wiring harness (pins 4 and 6) to the +5 volt terminal on the new supply. Connect all the GROUND wires of the game wiring harness (pins 1, 3, 9, and 10) to the Common terminals on the new supply. Connect all the +12 volt (pins 5, 7, and 8 ) AND the +21 volt (pin 2) wires to the +12 volt terminal on the new power supply. The +21 volts was for the audio amplifier which will work fine on the +12 volt connection.
Pinout of J1:
1 is Ground (black wire)
2 is +21 volts for amplifier (green wire) [can be connected to +12 volts instead and still work for sound]
3 is Ground (black wire)
4 is +5 volts (red wire)
5 is +12 volts to coin door lamps (wire color varies from machine to machine, but is usually blue)
6 is +5 volts (red wire)
7 is +12 volts to remove/throw darts lights and pushbutton lights (wire color varies, but is usually blue)
8 is +12 volts to monitor (blue wire)
9 is Ground (black wire)
10 is Ground (black wire)
