I have 2 x 12AX7's in a preamp and I was wondering who made these valves?
Cheers

Hi, You will need to find the tube code if possible? National Brand was a re-packager of other brand tubes, both good and not so good. Regards Norm

Is that a place?

No Dale, It is printed on the side of the tube towards the bottom. They are lightish grey and very hard to find it will be a symbol and numbers such as *24D ect., Regards Norm

Actually it is starting to look like China but not sure.
Norm I can find any marking s as you described.
Red markings say 12AX7A/ECC83

Dale it is of Russian manufacture. They are the ones who use pointed pins. Could be from 3 different factories. Regards Norm

A mate posted this on another forum as I asked for you over there as well.

"The Nationals that are made in China are sold locally by Wagner Electronics Services, WES, in Sydney. I haven't used them in years, but when I did they were just average valves, no better or worse than Sovteks but not in the same class as JJs or Winged C Svetlanas."
