Does anyone know the history of this company?
Are these tubes made by Brimar in line with the quality of Mullard?
Was there a piticular factory and location of this company
Thanks

that is what I have heard...
From Wikipedia: "Brimar, which stood for "British Manufactured American Radio" (valves), used all American designations. Brimar/STC was a UK subsidiary of the American giant ITT (International Telephone and Telegraph)."
FWIW.
Whoever wrote that article got a lot of stuff wrong . Brimar , for a start stood for British/American and was not a subsidiary of ITT until the 1970's . It was originally part of the STC group of companies . Thorn/AEI/Ediswan/Mazda were also members of this group of companies

They did have there own facilities but many were in fact made by Mullard.
In general they are good tubes.
Many ? I would have said a few .

I believe the tubes are of high quality build & sonically. Brimar 13D5 is best 12AU7 I heard. Brimar CV4004 is top rated 12AX7 & as good as Mullard 1950s 12AX7 long plate with slightly more neutral sonics. The Mullard long plate is very musical as well.
I agree with Neff on the 13D5. Great tube!
I've run Brimar 6V6GT (CV511) tubes for a long time. They work very well in guitar amps. Brimar makes a lot of mil spec tubes. Perhaps, part of their history is involved with supplying valves to the British Armed Forces?
May be some confusion here . Just about every manufacturer made 'mil spec' tubes . These so called 'mil spec' types are actually ruggedised meaning they were designed to function in harsh environments . Any ruggedised valves (apart from the old CV1/2/3 types used as proximity fuses in WW2 shells) will typically have CV4xxx codes such as CV4079 , CV4004 , CV4003 , CV4024 etc . Brimar CV511 for instance is just a 6V6GT with low loss micanol base . Nothing 'mil-spec' about it at all apart from it would have been used in government owned equipment , not necessarily for the armed forces
