The converter tube confused me a bit which is why I wasn't completely sure if it was a 40-180. It should be a 6J8G, but I don't think the 6J8 was ever was made in a GT version.

It looks like someone substituted a 6A8GT for the 6J8G. Although totally different in construction, they are pin compatible and might actually work in the 40-180 as a sub. Sylvania mentions their compatibility in an early datasheet:
