K.R.C. is Kingston Radio Corp. IIRC, they took over the radio biz from Fairbanks-Morse when they divested from home products.
It seems that they only made radios for Wards, Gambles and Western Auto.
I have a Coronado console with PP 6L6's, that is Kingston built, pre-war. It appears that all their line operated sets were transformer powered, which is fine with me.
