More Mullard:

How about these? All printed 'Mullard 6J5GT British Made'

And to finish the pictures this evening with some more tube porn. A few US tubes tomorrow.

I believe these are also Mullard? Foil getter.

This one's quite interesting. I think the Mullard tubes have those extra support rods quite consistently and they're absent here. We have a notably different bottom mica which looks like it was design for those extra support straps you often see on the RCA/GE models, but the supports themselves are not here. The grid posts are copper too, Mullard tubes typically use steel here.

It actually looks a lot like a Ken-Rad to my eyes, but I would not go so far as to suggest it is one because there is no evidence that Ken-Rad tubes were ever exported and re-branded during the time Ken-Rad was actually making these.

Also, man there is some tube porn being posted here today!

I'm increasingly of the opinion that when it comes to 6J5 the motto should be "don't worry be happy" as long as you like the sound and they match. The amount of cross-branding on these tubes is crazy. It is fun to try and figure it out though.

Boom! You nailed it. I also took photos of my US metal base tubes and indeed this is the same construction as KenRad. Will post up the photos tomorrow.

Awesome tube pron @leftside

At some point I need to add a pair of Mullard 6J5G

For me. This would be.
Mullard. Brimar. Sylvania.

I can see that....love the extra support rods on all of those Mullards....sexy!

My 'Brimar' 6J5GT/G that I have posted about previously look to my uneducated eye the same as these. They seem to have some kind of bottom getter on the same side as the foil. This can also be seen in one of the links to that bay that I posted previously. They are marked with white lettering and numbers inside on the pinched glass structure. The one I am looking at now says A43. (I'm sorry, I haven't found my Kodak Instamatic yet)

The orange lettering on the glass rubs easily off. It says Brimar BVA. To the left of this you find 10 and below 10 you find 1. To the left of 1 is a 4. It's not 41. Some letters above Brimar has almost totally rubbed of. The metal base is corroded. The remnants of the text on it is also orange.

A photo says more than a thousand words...

Same as KenRad. KenRad making tubes for Brimar....

I wasn't sure about the tube on the far right. So here we have another US manufacturer, in this case Sylvania making a tube for Mullard... And here's a Sylvania tube marked Sylvania (same construction as the Sylvania/"Mullard" from above).

If your "Brimars" are identical to these, then they are also actually KenRad manufactured. Good tubes btw.

They look the same or very similar. Do these have a sheet metal bottom getter with a wart on it? Any lettering on the pinched glass innards?

Now the question is; who made these for Ken-Rad? (I seem to remember that one of the auctions I linked to previously was a Ken-Rad and the other a Brimar).

Yes - foil getter. You can just about make it out in the pics. I'll check for any lettering, but can't remember seeing any.
