ARS Tubes


i pulled the original drive tubes from my VTL MB 185 to do some tube-rolling. The original tubes are labeled as ARS -- "since 1947". I've not been able to find any info on this brand of tubes. I'm sure it's because I'm new at this and "ARS" is probably code for some other manufacture, but it would be interesting to me to know the actual details. Thanks for your help.

Newbie: Thanks for your help -- what appears to be the original label on the tubes I have is in the form of a replica tube with three sort of halo-like circles around the top part. The tube is identified in the same color (as the replica tube label) ink as: Ecc81 -- ARS appears to have stamped 12AT7 on the tube. Any clues as to who original manufacturer might be?

Thanks again for your help.
Fatparrot: Thanks for your suggestion -- I looked up a picture of the Bugle Boy and the replica tube on my "ARS" tubes is much smaller and a bit more abstact in form. It's also printed in color -- gold or tan (I'm sort of color-blind).

Thanks again for the help.
Newbee was 100% correct, ARS was an outfit in the 80s-90s based in So Cal. My understanding is that with Power tubes they simply matched and sorted common current production tubes such as Chinese, Russian, Yugo tubes. I cannot say for 100% certainty, but I do not believe the smaller ecc81 tubes were NOS, rather they were also common Yugo/Chinese/Russian types.
Justlisten, I seem to remember that they acquired the rights to the Amperex name and logo a few years ago. I believe that these new "Amperex" tubes are rebranded modern tubes, and should NOT be confused with the good old NOS originals.
