Proceed HPA service manuals

Does anyone know where you can obtain a service manual for the Proceed HPA series of amplifiers ? Apparently these are hard to come by. Much appreciated.
Here is the manual for the HPA 2 , but not sure if this helps you or not ?

Is there a different model that you are looking for other than the HPA 2 ?
Thx for the replies. I am actually hoping to find a service manual as opposed to the owners manual. The model in question is an HPA 2 that has the dreaded "locked in standby" that is very common to the HPA series.

My tech. has thus far not been able to locate any circuit diagrams as they are hard to find.
Last month there was a member with a problem with his amp also, here is the thread :
