My vote for Lafayette KT-600 of the 1950's.
Warm and accurate in sound, versatile with 6 tone controls, and using the ubequitous 7025 (12ax7). There are three types of facia, of which the first is probably the most outstanding, with beautiful lettering in the lower centre, mustard caps inside that last a useful lifetime, and therefore sound consistent all these years and need the least hardware maintenance.
The bonus is that they are not choosy with tubes. Mine goes with 2 12ax7LPS (phono), 2 RCA long grey plates round getters (tone), 2 TKF ribbed (line), and an unknown one (for the center line output and the calibration drive).
