OK, I have posted pictures and videos of the substitute tubes in action.

My one conclusion that is not in the blog is that the sub may actually be more suited to a low performing tube rather than the NOS ones I was using - closer to 600 Gm.

Don't forget to like the blog post. These posts take days to prepare.
