Conrad-Johnson MV55


What I need to do is replace all the components that have been overheated or strained, and remove the burned areas from the board (because burning - or more accurately, carbonisation - makes these areas become partially electrically conductive instead of acting as an insulator). This photo shows the result of that process - the red colour on the burned area is special insulating varnish which is applied once the burned areas have been cleaned up and the components replaced.
