Hi, You can download the complete service manual including the schematic diagram also. Here is the link. Unfortunately there are many possibilities of faults and so I can not give you any solution. You should have given description about the problem. When you get to the site using the link it is possible that you have to wait a little bit to be able to download. After waiting you should see a button as "Get Manual" and simply click on it and save the file. Thanks. gylacz
The surface mount ic= MC33079D , 14 pin quad low noise op amp is likely at fault, IF the amp is NOT showing a fault light. A LM324D surface mount will also work in a pinch. It's located on the input pcb attached to the input jacks.
I do not believe that these are available outside of authorized service centers. Can you please describe the problem you are trying to resolve? Also, Crown amps are not the simplest in design. Use caution when working on these, there are high voltages present throughout the chassis. You can contact Peavey Corp directly to purchase a service manual if they are available.
