before i turn off the soldering iron , george of the jungle....
will you tell me exactly what you did to connect your meters to the dcp board ???
i want to do that....when i first developed problems...and had dc on the outputs...
pegged the meters...i think that wont happen if hooked to dcp and it is functioning...
please....
thank you for all...
Remove your meter signal wires from the back wall or backplanes. Connect the right meter signal wire to the red speaker jack stud that's screwed to the DCP, and the left meter signal wire to the white speaker jack stud that's likewise screwed to the DCP. I used a ring terminal for a #4 stud or screw(4-40), and 22 AWG Teflon insulated wire, black heat shrink and a small piece of red for right channel, white for left. The ring terminal goes under the screw head and contacts the trace and screw for the respective channels jack. All we're doing is changing the location of the signal wires from before the DCP relay, to after the DCP relay.
Easy to do if you have the parts.
Congratulations on reviving your dead amp. Excellent!!!

Like my BlueTooth ?
Glad you like that piece of Schiit btw. I still got two of em and I like em just fine for less than 200, a nice DAC. Hell, the Modius has balanced outputs as well and still 199.00 shit, I can't beat that.

if you ever hear scratching and pops and clicks on power up....its gonna be a bad day...both the 400 and 200 started with that...and to be honest...i made mistakes that cost me also...
sniff and the gang are right...this old stuff is very difficult and fragile...one thing leads to another...
however...i have gained so much....
thanks!!!

Does not Matter (can spaces the fans were you need them I put it behind the amp and blow into the Transistors
cuz I make my own.
I use DC computer fans w a 12vdc PS
Pic of simple one,
It has a cheap computer Fan control, 4- speed adjustment pots
and one of my home made one w 2 Fans . I have some base's made of wood and the power is a wall mount 12vdc PS
Pic #2 I just built a New one w temp displays and Fan Control
I love the Pioneer gear! I also have some SX-1050 ,, SX-XX50 and RG-2

Oh my electronic teacher was asked what kill Stereos , He paused,, and said Heat destroys everything
I than added fans to my Phase linear 400 II
