My Eddystone collection stared out with a 730/4, and I also have a
750. It seems reasonable to assume that the 750 dual conversion
technology would have been available to Strattons when the 730 was
being designed. Now, there are many nice features on the 730/4 that I
wouldn't do without and which were pricey at the time, so I wonder why
it was a single 450kc/s IF and not 1.6Mc/s + 85kc/s and hence 888
selectivity? The MOD was especially penny pinching in those days.
Regards to all: we've been busy with elderly parent problems so I
apologise for perhaps not maintaining this site as I should!
