Hi Gdolf,
I've been casually following the thread and it seems like you are slightly confused about the alignment. When you tuned the IF to 455 KHz the IF is aligned for both the SW and Broadcast bands. Now you can send rf signals to the radio and make adjustments to align the dial to the correct signal frequency and maximize the signal reception.
If what you indicated about the SW band is true, your radio is working fine except no Broadcast Band signals are getting through. Both bands are using the same circuits from the 1232 to the speaker so the problem would be with the Range/Band switch or the associated coils/transformers. To change bands the switch disconnects one set of coils and connects a different set. I would concentrate on the switch contacts and wiring. It may be a PITB to do but these are 80 year old contacts and need a thorough cleaning with a strip of paper and contact cleaner; be gentle. Also, be sure all the coils have continuity and have solid solder connection.
