I did the same thing with my Zenith Trans-Oceanic 3000-1. I was trying to peak the IF transformers for better reception, but I must have broken a wire or two or, Heaven forbid, one or more of the adjustable cores in the transformers crumbled. AM and shortwave are now dead, but FM still works as well as ever. I'm thinking the cores must be crumbled or broken beyond recognition by now; if so, I won't do any more with the radio since I have several sets with working AM, which I don't listen to that much anyway. I'd like to get the AM on my TO working again, though, as this radio has an RF stage ahead of the Wavemagnet antenna and can be a real DX machine when it is working as it should.
