I though they need some more burn-in perhaps. Only the machines are the same, and in the Tesla days they were new, and now they are old.

They are regarded something different, which is correct. So is is used a cooling fin.
Most of them have yellow printing. The next difference I noted, are some costs savings on the shielding. With this tube there is a shielding plate between the two triodes. The shielding plate was coated black, and is used to transport the heat out of the tube center. Well ok, JJ is new production, so I thought this was the explanation. This is one difference. Many people thought this situation would always stay that way, and the TESLA management thought so too.
Same as with all NOS when I see that. What a quality this is! So I let the tube run on the tester, and the next day it was testing weak. The used materials definitely are not the same.
Then I let one tube warm up, and apparently it started to reduce plate current slowly. First of all, the needle of the tube tester goes up faster as with the JJ’s, and that gave me a good feeling.
In the below picture you can see this difference clearly. Russians and Chinese tube factories raise their prices twice a year due to higher energy costs and higher cost of all kinds. This was curious, because with NOS, I never had this. There was enough NOS around.

Then after the initial heat-up, the Tesla’s change their readings only very little, and give a totally stabile reading after just minutes. Identical tools are used Another difference is in the part numbering. These are little jewels. These are from the ‘s.
I sold this lot where it e88cd How typical for Ebay. Oh well, I thought one bad tube out of 20 can happen. Then they keep just this value no matter how long hours or days I let the tester run.
I got a higher price than expected, and the buyer was satisfied he wrote me. Here you see a close up of the gold plated grid bars coming out of the mica. Also wires, and nickel technology came from Tesla plants that are all closed now. On my tube tester Metrix U61B initially they tested very nice.

The machines were moved out of the building and reinstalled at a factory of a man called Jan Jorgo, better known as JJ. So obviously they did not use just gold plated grid wire, they gold plated the complete s88cc after it was made. I wrote in the Auction why I sold them, and they were with the option to return if not satisfied. Bidders were fighting for them.
This is great, because the center anode plate is already hotter than the outside anode plate.
