Been putting the final touches on the NC-303. WD-40'd all of the tube sockets, pots and wafer switches, cleaned and aligned everything, replaced the HV supply cap and installed a new audio transformer for 8-ohms out. Also replaced the SO-239 connector and replaced the power cord with a nice long grey colored 3-prong grounded cord. Just have a couple of more things to go and it's finished. Not too bad for a 1958 thru 1962 vintage ham bands only receiver. .
