What was the rational behind Philco using an autodyne oscillator in the later model 90s and the 91, 71, 89 etc? Was this a scheme to cut down on the number of tubes or was it another dodge to avoid paying royalties to RCA? I would have thought Philco would have stuck with whatever worked as a front end rather then re-inventing the wheel, but then again not everything Philco did was exactly rational.
