phase linear 400

You haven't removed the Zobel Network from the DCP.

 

[George S.]

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.

 

[George S.]

Gene, didn't you already remove a Zobel Network from a DCP? Hope your not running it in one of your stock amps.

i removed the resistor caps assemblies on speaker jacks before installing dcp...i thought that was the zobel network...because one is built into dcp...
yes...all units are running stock dcps...

 

[gene french]

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

 

[George S.]

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.

i removed these from the 4 fin and 8 fin before installing dcp....the wopl used joes new chassis and meters and transformer from a parts 4 fin i bought from rob...

black wire was included in dcp kit i installed in other two..i did same in wopl...

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...

 

[gene french]

i am sure i am ok in the 4 fin and 8 fin as far as the zobel network is concerned

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.

you removed two r1s and one c9???
for disabling zobel on dcp???

ok... i was aware on the original pl400s...
but was unaware about the wopl...
thank you sooo much...

 

[George S.]

Also C8, 2 resistors and 2 film caps, they are in series. Look closer. Holes are soldered shut.

 

[gene french]

You still have a white meter signal wire soldered on the left backplane.

what is designation???
i was not aware

 

[George S.]

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.

r1, r2, c8, c9...
got it

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
