If the local oscillator is gone, dunno how you picked up a station. Pentagrid convertors are rather straightforward.

You may have to put the test radio (the good one) under the chassis of this radio near the local oscillator with the test radio dial set to about 1100KHz, then "sweep" tune this set, listening for squeals in either set. This radio has an RF stage which kinda shields the oscillator from emitting like a 5 tube set does.

I hear you regarding the frustration. I worked on a Philco 89 from the 7th ring of you know where, with a tetrode autodyne convertor stage for close to a year before I got it working.
