I have a onkyo M-504 that has 2 channels blown.
Does anyone have a substitute for the outputs?

Why not just buy the originals??
Seems they are easily available from respected sellers all over the world for between 6 to 10$ a piece.

At the time I couldn’t find I used the sub replacements that Perry suggested and the worked flawlessly
Yes only one output was blown but rebuilt both channels and biased per service manual. I have clean audio but I now have a different issue I noticed that the speaker selector switch that control the mechanical relays are not latching properly and are chattering, I physically have to hold switch in to get audio out. Not sure if it’s the front panel switches or relays
You can always bridge the switch contacts to eliminate them from the equation.
Make sure to check for DC offset on the speaker outputs - in case there is a good reason for the protection relay chatter..
