Progress continues tonight on the National NC-101X project. First real desoldering and parts replacement work. Remove and replaced dry rotted old line cord and chassis feed through grommet. Installed new a three wire line cord, with grounding chassis, for electrical safety.
Tomorrow evening I start with replacement of the old wax paper capacitors, 21 total. Then onto the replacement electrolytic, reinstallation of the moving coil assembly, paint some Extend rust convertor on the bare chassis spots, and finish off with an alignment.
