There was a special Sylvania 6l6GC version spec’d by Fender many years ago.
Later on (early 80’s?) Mesa Boogie spec’d their own 6l6GC, but I’m not certain who manufactured it.
Maybe try a guitar site/forum?
I checked the Tubemonger tube library (great pics of tubes) but didn’t turn up much on the 6l6GC.
