I aligned the IF to more or less 5% of 260kc with my transmitter and several strong local stations. It didn't change much, it oscillates down to 950kc, so a little step in the right direction.
In the process I managed to somehow mess up the dial calibration by 20kc or so. I think I'm going to put this to the side for now, and look for an rf generator to do it correctly. In the meantime there's the cabinet and five more Philcos to work on
