Yamaha MS40DR Electronic Drums Monitor

Does anyone have a schematic for this amp?
Yamaha in the UK are being very anal over both supplying and whether it even exists

There may be one here Yamaha MS40DR service/repair manual, schematic diagrams
Yamaha will not supply manuals to the public, only their service dealers and we have a contract with Yamaha to keep them 'in house'.

I had seen that Jon but I'm not about to pay USD19 only to find out that it's a user manual which is all Yamaha could offer (that's assuming that they know what a schematic diagram is). I'm hoping that someone with electronic knowledge has what is needed
