Hi there. I have a problem with the above amp.The right hand channel has a d.c offset voltage of about 2 volts across the level control. I have replaced the balanced input I.C( a MC33079) but it is still the same.Any suggestions? Many thanks,Gwyn Davies,Wales.U.K

Hi there.Does anyone know where the 3 way plug with red,blue,and white wires terminates? the 3 wires go into the fan windings. I cannot see anywhere for the plug to go! Many thanks,Gwyn Davies.North Wales,U.K
