Problem with Production mixer 902

Archived from groups: rec.audio.tech (More info?)

Hi
I have 2 Production mixer 902 from Peavy.
Both suffer from same problem : sometime, one side of the stereo mixer
main output doesn't work.

I used put a fan on the mixer and recover the missing channel.
Now, doesn't work anymore, look like the problem is getting worst.

Anybody has a tech manual in electronics format so I could try to fix
them ?

Thanks
