schematic for yamaha em-80 mixer

[Seditionary]

hey all !

was wondering if anyone had a schematic for this mixer..  my reverb went out in it... want to try and use a signal generator and listening probe to see where it went bad. 

thanks

bump.  fixed the reverb... was just a bad coil on the reverb tank...

but now i want to fix the headphone and speaker output (which are not working)... unlike the monitor out (which is working)... the speaker out goes to a separate card in the back with two amplifier cards.  maybe it could be an amplifier card... maybe something else.

anybody have a circuit diagram or schematic for this mixer?

thanks!

the user manual is available online... but it doesn't have a schematic in it. 

thanks for your help if anyone has the files!
