Regarding the third version 90:
Yes, they went to push-pull 47 outputs which is nice, but they cheapened the front end by getting rid of the separate oscillator tube and adopting the "autodyne" circuit; i.e. using a single 24 as mixer and oscillator. A poor design then, an even poorer design now. Ask anyone who owns a Philco 89 or 19.
