A long time ago (10 years? 15?) I had a 75S1, it did not have any filters, just 2 back to back IF cans, and it was about 20Kc wide.
I should have kept it, with the addition of a kiwa 6kc filter, a low distortion AM detector, and outboard audio, or a nice solid state audio power output, it would have made a nice ssb/cw/AM receiver. Very nicely built, nice looking, small and light, stable and accurate, tubes, good stuff!
