I bought a Peter Chou switching PSU to replace the power board in my Gorf cab, but am not 100% sure on converting from the original 19 pin wire harness to the switcher. If anyone has experience with converting a Gorf (or any cab, really) to a switching PSU and could verify the below listed pinouts, especially the stuff in italics, I would greatly appreciate it! The top is what is listed in the original docs, the bottom is my best guess on how to connect it.
1 +V Audio (~13V @ 1.5A)
2 -5V @ 0.45A
3 +V Independent [~10V @ 3.5A, to coin door and control lights]
4 !Reset
5 V.Batt?
6 Key
7 +12V @ 1.45A
8 +12V @ 1.45A
9 -Sense
10 AC Sync?
11 -V Independent
12 -V Audio
13 Gnd
14 Gnd
15 Gnd
16 Gnd
17 Coin Counter Drivers (~8V, unreg +5V) [from coin meter]
18 +5V @ 3A
19 +5V @ 2A regulated for logic
1 +12 on switching PS
2 -5 volts on switching PS
3 12 on switching PS
4 reset-- +5 volts on switching PS
5 not used?
6 key
7 +12 on switching PS
8 +12 on switching PS
9 -sense --ground on switching ps
10 not used?
11 ground on switching ps
12 ground on switching ps
13-16 common for all regulated outputs
17 +5 or 12 on switching PS - unsure if this should be +12 or +5, since original was unreg +5 and ran about 8V
18 +5 volts on switching PS
19 +5 volts on switching PS
