phase linear 400

You have a ground wire going to the RCA copper plate. The copper plate gets grounded with a wire or coax shield from the control board.
I'll stop here. That's the big stuff that jumps out at me.
 
Gene, didn't you already remove a Zobel Network from a DCP? Hope your not running it in one of your stock amps.

That black wire your using for "AC input from transformer" for the DCP should be red if you have the wire, and continue to run across the top of the right backplane, then down to the connection on the DCP.

i used black because was in directions of dcp on the two before the wopl
 
Joe has the Zobel Network built into the backplanes. Don has the Zobel Network built into the DCP. When using Joe's backplanes, the Zobel Network must be removed from the DCP. Each channel has that big resistor and film cap in series. You can do it quick and dirty by cutting a resistor lead, or remove the components and solder the holes shut for nice appearance. Let me find a photo.

400 DCP with each channels Zobel Network removed for use with WOAD backplanes. Relay is temporarily removed for better visuals.

that makes sense ... i will disable along with seperating flying wires and ac feed to dcp...

You did good. You removed the original PL Zobel Network and replaced it with the new one built into the DCP
When you use WOAD backplanes, they have a built in Zobel Network, so the one on the DCP must be removed.
There must be only one Zobel Network.

ok... i was aware on the original pl400s...
but was unaware about the wopl...
thank you sooo much...
 
Many of my photos are older, and I try to find the best ones to illustrate a point. I've gone back into my amps several times making minor upgrades. That photo of the DCP shows grey wires feeding signal to the meters. They now actually have the correct red wire for right channel and white for the left.

Left backplane, beside the flying yellow output wire. Photo shows white wire soldered in, one on right backplane looks cut or broken off.

out 1...says to meter...on light board...
i need to disconnect and use two wires from dcp...
i forgot left side...i removed right...
but i do need that white wire to the light board but connected to ground...and not out 1
