The 70s gear is nostalgic (been through this hobby’s evolution from 1971 onward....) and that’s where the sentimental bias floats through.
the cold hard facts are that this old era gear cannot compete with the current era offerings.
I would strongly suggest that you personally audition/test-drive something current before you commit more repairs cashola to the old stuff..... the differences in performance improvements are not subtle.
This exists without prejudice to the fact that that old gear ... especially the Sansui .... has a questionable and minimal FMV thst is highly likely less than what you will fork out now, and it’s only a question of "when" the next round/stage of repairs arises.
