Anyone got a circuit diagram for one of these or know where to obtain one? My Aura PA-200 power amp was working fine as usual last night. Today I switch on and zilch it shows no signs of life, so I check the mains input fuse and it's totally black inside the glass :( Probed about with meter on the obvious things like rectifier diodes but nothing obvious shows. The mains transformer has a couple of quirky readings but without the circuit diagram I can't be sure if it's correct or not. I'm getting the DT's already being without my music :(
