easyone Posted February 24, 2018 Share Posted February 24, 2018 Does anyone know how to ID where this tube was actually made and by whom? I have found conflicting opinions around the web when I searched. There are cross seams on the chrome top of the tube. Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted February 24, 2018 Share Posted February 24, 2018 Are there any other numerical codes on it. Quote Link to comment Share on other sites More sharing options...

There are no etched numbers. Only those you see in the pics. Quote Link to comment Share on other sites More sharing options...
thebes Posted February 25, 2018 Share Posted February 25, 2018 There is no hole in the center pin so it's probably not Mullard, and I forget the name of the other big maker in Britain. Quote Link to comment Share on other sites More sharing options...

Are you thinking of Brimar? I think the tube was made in Japan at a facility Mullard helped set up - because of the cross seams on top. I read that the seams on top were a sign of a Japanese makers tubes. I cannot remember where I read that. 1 Quote Link to comment Share on other sites More sharing options...

thebes Posted February 26, 2018 Share Posted February 26, 2018 Wasn't Blackburn the Mullard factory? Brimar was indeed the one I was thinking of. Japanese made tubes were usually labelled that way. Quote Link to comment Share on other sites More sharing options...

thebes Posted February 27, 2018 Share Posted February 27, 2018 From the Jesse article: "BEWARE: late 1970s production Mullard and RCA (labeled Great Britain) that have crossed seams in the top glass were made in Japan! These are not Mullard UK made tubes, although they were made in a Japanese factory that Mullard helped set up and are decent tubes.

Guy Landau Posted February 28, 2018 Share Posted February 28, 2018 It looks like a Japanese tube made by Matsishita . Quote Link to comment Share on other sites More sharing options...
