Yes, it's working very well with my older tubes
I have other testers I can use for newer tubes.

I sold the MX-949/U adapter a long time ago. I do not miss it - they are a pain to use.

Yes, I finally noticed the 52 on the nameplate and on the manual
I had a feeling the MX-949/U is a pain with all those patch cords.
