Here is my Zenith 7H920, similar to your H725. It is a great sounding set with more volume than I would expect from a SE output design. I tried doing a sweep alignment of the FM section but could never get the marker blip (10.7Mhz) to show up to set the discriminator properly. You can see the results in my post about Eico 368 Sweep generator in the “Test Equipment” section of the phorum. I was able to get aligned on the money using the crystal marker only and it sounds great. When you get to aligning yours it should be doable with a non-sweep generator. Looking forward to your progress!
