Several announcements were made in 1928 about the manufacture of tubes/valves in England.  A typical one from September 1928 is below.

Is it known whether tubes/valves were ever made in England?   

Are there any Loewe tubes marked "Made in England" ?

Although it would seem that radio sets were at least assembled to a new design in the UK,  It is likely that valves were never made in Britain.   This was probably because the demand for such multiple tubes declined quickly because of the difficulty and cost of manufacture and the associated competition from other manufacturers.  However, any information would be of interest.

Regards,

Roy

Dear Roy

Yes, there are several LOEWE tubes with the marking BRITISH MADE like this one:

Another example is the RNF7 depicted on the tube page.

Kind regards.

Dear Wolfgang,

Thank you so much!!   It clears up a puzzle for me as I have not found any firm evidence before in the literature.  I should have looked more closely at the tube picture!

They must be very rare as the quantities manufactured would have been quite small.

Thank you again for the information.

Kind regards,

Roy
