    Ok i have it wired up but it's nothing like the switch pdf in 31 shows. i found a pic somewhere on the internet. This transformer isn't like the other 2 I have.
    but i took a pic and uploaded it here of what worked I think this particular one is a cs-800A no triac on switch. It's on the long bussbar bottom right side.
    Now I have it back and powering up I'll check voltages.

      IMO, that means the transformer is most likely good. Here's some documentation on the power switch including switch schematic. One side of the rocker switch (if that's what you have) is for the internal neon indicator lamp.

      With switch on, I'd check to see that AC is getting to the transformer primary measured right at primary leads.
      No its is not but the fan comes on, which boggles my mind I'll see if i have another switch I can sub in for testing.

        Didn't properly bypass thermal breakers. Now that that's correctly done i have +- 81 and -+15 volt rails. Next what I'd like to do is get a replacement molex plug and pins for the power output boards.
        Any suggestions pics included There is one post missing off the power board(It came to me with wires soldered to board)

        !st pic is the molex for one side 2nd pic is powerboard with one post missing, 3rd pic is splayed wiring

          I haven't been inside a CS800 for a while, so add grain of salt. Peavey typically had one pin opposite gender in their board connectors so that you couldn't plug them in backwards. I'm not 100% positive that's the case here. That is going to make it difficult to find an exact replacement, unless maybe Peavey still has some. If Peavey support was still worth a shi+, I'd tell you to contact them. Otherwise, lots of Peavey amps used those connectors. Maybe someone will have a donor you can cob a connector from.

            I think I can make due with this kit. Based on some other of Enzo's threads the .093 are the ones we want. And i can make the needed config.

              Ok I have the connector completed . Now i need to find the post that mount on the PCB. Wish i could ask Enzo as he would know.
              Anyone else maybe have a source?

                If you got both gender pins for your connector, take the one you need from that connector kit and solder it to the board.

                  Due to someone posting a link to an arcade supplier i found that the connector is called a Wafercon pin. So i am ordering a few pins and will let everyone know ow it runs out.

                    Here is what I settled on that works. I just swapped the pins around to fit keying order.
