Do we have any experts on Brimar novals here? I’m trying to get some insights into how their different model ranges (regular v industrial 13dx v Trustworthy 60xx ) and generations compare sonically on the ‘at‘ and ‘au’ types.

Reminiscent of schoolboy memories of King Edward’s fate at Berkeley castle.
Any insights into this orphan I found in my stash? Fortunately my Riviera headamp only uses a single 12au7 so I should give this one a whirl sometime.
A rare tube equivalent to the 13D3. It has a gain of 30 mu, higher than the 12AU7's 20.
"Brimar" was just a registered trademark, it was the abreviation for "british american made tubes". They put their logo on tubes from different manufacturers they purchased in great batches. You will have a hard time to find out, what tube manufacturer was behind each specific Brimar labeled electron tube.
Here's my small tube stash.
Brimar did design and manufacturer their own tubes for many years in a couple of UK factories. Along with Mullard, Marconi, and others they formed a consortium to protect their UK interests.
Brimar and Mullard had some unique plate designs and now fetch very high prices.
In later years after Brimar was acquired by Thorn Lighting, other manufacturer's valves were rebranded Brimar.
OK, new part of their history. In later years, they rebranded valves from other companies.
BRIMAR is a "brand" born in the UK in 1934. Its history starts with American Western Electric which in 1883 opened a small office and shop in London. In September 1925, the International Western Electric Company was acquired by the "International Telephone and Telegraph Company (ITT)". In Great Britain this company grew considerably and took the name of "Standard Telephones and Cables Ltd. (STC)". STC first used the brand name "STANDARD" for its valves. From 1932 to 1933 the valves are called "MICROMESH" and since 1934 "BRIMAR" In 1960, Brimar's valves and cathode ray tubes division was sold to Thorn Electrical Industries.

I know collecting is fun, but do you have any idea of the price for one square-getter these days? I think I paid $300 for a true NOS about 3 years ago (Vintage Tube Services).
I see there is an initiative to restart production of Brimar valves here in UK using original machinery

Yes, they've been at it for a few years now. I admire their ambition.
They were selling "NOS" tubes and branding them as Brimar, I see they've stopped due to the current worldwide mess.
