Does anyone have a main board layout diagram Ensoniq EPS original? (1MB RAM version)  
I have the schematics and service manual.  
On the actual board most of the component numbers are underneath the actual components.  
I’m hoping to go over the output filters with a scope but it’s impossible to find the component numbers.  
Thanks,  
-Ivan

Unfortunately not everything was meant to be serviced. This is such an example. The service manual is not really a service manual, but a trouble shooting guide.

sorry.
