Get rid of any old caps on the ac line terminals, the cap is usually on the cheater cord terminals before the fuse and if the cap shorts you will not have the set's fuse to limit the current. also if the cap goes to the chassis and it shorts you will have a hot chassis and not know it.
I have seen these burned wires too in ctc-16's...one thing to do may be to replace the wire, dress the lead away from the heat producing resistor lead and also put some heat shrink tubing over the wire, this will act as higher temperature insulation and help protect the wire from heat being generated in the region.
I was able to find 3/4 amp fuses at rat shack at one time...however they may not have them anymore. WHat circuit is that in...you may only have 300 ma of normal current and a 1/2 amp fuse may afford quicker protection and still withstand the normal current in circuit.
