The Signetics and Philips TDA1034 versions are considered the best ones. They are 1976 vintage so they are out of date, opamp wise. No, they don't need replacement like caps or tubes unless they have degraded from original specs. An upgrade to a newer device is highly recommended like the National, BB or LT parts. You wouldn't run a Commodor 64 or an Apple 2 today would you? That's how old these designs are now.
