where did you find the info showing these two to be autogated pinnacle?
I have not found it in the sense of word you might expect. There is no source that would help you reveal this, I am afraid.
Dino is right, I have spent years collecting all available info. That included saving all pictures, writing down all found records, comparing serial numbers with power supply types etc. No one has "taught" me this but many fine guys on various NV forums have helped a lot by providing info about their tubes.
After a while the whole system starts to make some sense. Most tubes are easy to comprehend now but I dare to say that there are 5-10% tubes which still give me headache. ;)
Yours are the easy ones :)
Care to check the numbers scratched on the sides of your tubes, in return, and provide me with info for my database?
