hi! this is my first post since registering, accidentally touched the speaker wires together on my nad 701, and now it sits in protection on and off, with no sound. anyway, there is 1 resistor that is blown like a marshmellow, and i'm having trouble finding the schematic on line for it so i can figure out the value. it's part r453 on the lower pcb a few inches north of the main caps. any help either with the value or locating a schematic for purchase would be very very much appreciated. would hate to moth ball this thing for a simple little resistor. thank you!!
