Maestro Sound System For Woodwinds, Schematic needed

[pdman]

Hello

My Son recently picked up a Maestro Sound System For Woodwinds,
Model WM2. I have been looking all over the net for schematics for this unit.
So far I have had no luck in finding anyone or anywhere where I can either download or buy a schematic.
Does anyone have any schematic for this box and or know of anywhere I can order a schenmatic?

The unit is in great shape physically and works OK electrically, but I believe 2 sub octave circuits are not working when the associated Tabs are engaged.

I really need help on finding a schematic for this unit and any help is greatly appreciated.

Thanks

Thanks
I know this place and somehow missed them.
They do have the service Manual plus schematics.
I will be ordering.
Again, Thanks
