Service manual for Primare a20 MKII

HI
I am new here, because I am urgently in need for this manual.
I found this thread via google and would be very happy to get the manual.
A friend of me has this amp and asked me to repair it. There is some fault in the speaker protection circuit. Sometimes it works for hours and sometimes it switches off and on by its own.
Please send it to my mail addy, many thanks.
