like the title said, does anybody have a schematic for Allen&Heath SD12-2 to share with me?..I sort of accidently just bought one..I need a new mixer for my bands rehearsal space and this one came up on a local site for about 50euro's, so I couldnt keep away..at least it looks cooler than a b-ringer..discrete pre's, 4-band eq, monitor and fx send


..it has two dead shanels, but I figured it's probably just a bad breakjack, a dead opamp or an brooken fader, so why not?...but a schematic would be nice...
thank's

Heh, that second picture is my mixer on my kitchen table.   ;D

I've got a partial schematic in pdf form.  I just finish recapping mine and socketing the opamps for a future upgrade.

I'll post it somewhere.  Give me a minute...

Here you go

yes, that was the only pic I could find that showed the whole front...and also, the pics from the inside, showing it is modules instead of a single pcb actualy helped me decide I wanted it... :D
