Thanks for help and suggestions. The 6U8 mixer was microphonic (as is common) and replaced with a 6EA8 equivalent improvement. Nice!
Now cleaning rotor bearings in Main Tuning capacitor and hoping it all becomes rock solid!.
Will keep you posted.

The two best candidates are: 1 a microphonic tube,
2 a microphonic I.F. can. It could be as simple as reseating the tubes.? Just about every part and solder connection in the radio can become microphonic. Open it up and tap around with a plastic tuning tool or small wooden dowel.
