Sounds to me as though the front end mixer isn't working. You still need a local oscillator to oscillate and a mixer to create the intermediate frequency sent forward to the IF stages. Sounds to me as though the front end is not functioning as a superheterodyne. And the result is you're pulling in a local strong FM transmitter, perhaps on RF or maybe a harmonic. Your inductuner likely uses a 6J6 or similar in That capacity. Double check it is a good strong tube with good connectivity in the socket. You may find its a fast easy fix. If not, check the mica and ceramic caps within the inductuner to make shure they are not shorted.......
