Changed a few resistors. Some factory that do not agree with the sch, I left them, but those 500K that show 800K I replaced. One of them was AVC.
One was the detector amp load, after which the gain went up, now much louder.
But: though the speech is fine, the music is distorted, though it is only on the local station that is very strong, and others do not play any music.
I tried a different speaker, and changed every single tube, no change.
Replaced the diode with the 8.2uF cap after I lost the 43 tube and I only had one left, so I decided, it is cleaner and the tubes are not stressed anymore.
Plenty of stations on the BC, just one on the SW, but then thd antenna is short and it's not the night yet.
If the music keeps doing that (and it seems all is good electrically) I'll just leave it be.
I'll align it one more time, see if there's any change, though it seems the trimmers that dud not do anything still don't. Strange as the 456Khz seems go through well. Bad trimmers? Could be.....

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
