Linear tracking of that vintage had a nasty habit of wagging back and forth which actually destroyed the groove walls of the record. Studer Revox used a completely different system of linear tracking which did not wag and cause this irrepairable effect. Souther was more sophisticated and also did not affect this condition.
I would guess that your collection has sustained that damage and going to a new turntable would reveal that. Tough call here as I would not recommend repair. Find a Rega as suggested and find out if the collection is still listenable.
