I had the ballast in an old two tube T12 fluorescent fixture go bad.

The local big box had direct replacement LED tubes on sale, so I tried them. They wire directly to line current, no external ballast, but the tubes fit in the old tombstone connectors.

Did you disconnect the ballast inside the fixture, that connects to those old tombstone
connectors?


Yes. There were LED tubes available that worked on a ballast, and I considered doing that because it would allow a retreat to fluorescent if I didn't like them, or if they became unavailable. But my ballast was bad, and replacements were expensive. So I removed it and wired 120VAC directly to the tombstones.
