I have an Integra DTR 70.4 with no power. The relay coils are shorted, and the voltage across them are 5x what they should be.
Your thoughts?
I'm thinking an electrolytic went bad in the high heat Integra is notorious for.
I can try to fix the board, or just replace it, but I can't find it anywhere. Your wisdom is appreciated.
Thr to ignore the silicon job. It was that way when I bought it.

I don't follow. If a thing is shorted, how does the voltage across it grow? And why would a filter cap cause that?
I see caps, inductor, and fuses.

Guess I can't edit for clarity.
The voltage AT the terminal is 5x what it is supposed to be. The initial picture is only for part number.

You will not find a suitable replacement board unless you design it yourself.
Just test all the parts on the board and replace the bad ones.

This doesn't make sense - relay coils rarely (never?) fail short circuit. They should have back EMF diodes connected across them - which could indeed fail short.
Not too difficult a board to draw a schematic from - which would help us to diagnose the fault?

Update: replaced the relays and a couple caps, voltages are back to normal, receiver is back to full operation and sounds AMAZING! Pretty stoked.
Might add some cooling. A liquid cooled receiver seems a bit much, but might do it just for fun.
