was doing some work on my kombo and the back fell and the power and audio leads got pulled out of the board. So anyone have a picture of a PC 102 board so I can get the wires in the right place! Thanks

Sorry , I forgot that I no longer have a A series amp to take a picture of that 102 board from!
If others here can not help out with a picture then if you post up a clear shot of yours I can tell you what goes where, or now may be a good time to get down the basics of reading a schematic for that board from our technical section?!
Looking at your photos, here's what I could figure out. All of the wires go to the left side of the board. At the lower left there is a blue wire still connected that should go to the two input jacks.
The three wires that need to be connected are the black ground wire, the red power supply wire and the blue output wire that goes to the main chassis power amp.
The black ground wire goes to the top left of the board. There is a hole just to the left of the back of the volume pot. If you look at the copper side of the board, you will see the copper trace from that hole goes under the pot and connects to the metal pot case.
The next wire is the blue output wire. If you look at the board, there are two black plastic cased transistors along the left edge of the board. Just to the left of the top transistor is the hole for the output wire.
The last wire is the red power supply wire. Below the volume pot, there is a tall white capacitor. Directly below this cap there are two holes, one of which had a wire soldered in it. That is where the red wire goes.
