In the below picture you can see this difference clearly. Well ok, JJ is new production, so I thought this was the explanation. Only the machines are the same, and in the Tesla days they were new, and now they are old.

Same as with all NOS when I see that. First of all, the needle of the tube tester goes up faster as with the JJ’s, and that gave me a good feeling.

I though they need some more burn-in perhaps. There was enough NOS around. I sold this lot where it belongs: So is is used a cooling fin.

Bidders were fighting for them.

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 grid after it was made.


jh Also wires, and nickel technology came from Tesla plants that are all closed now. Oh well, I thought one bad tube out of 20 can happen. Then after the initial heat-up, the Tesla’s change their readings only very little, and give a totally stabile reading after just minutes. These are from the ‘s.

Russians and Chinese tube factories raise their prices twice a year due to higher energy costs and higher cost of all kinds. Many people thought f88cc situation would always stay that way, and the TESLA management thought so too. Well, then everybody is happy. So I let the tube run on the tester, and the next day it was testing weak. This was curious, because with NOS, I never had this.

The used materials definitely are not the same. With this tube there is a shielding plate between the two triodes.

Most of them have yellow printing. The shielding plate was coated black, and is used to transport the heat out of the tube center. These are little jewels. I wrote in the Auction why I sold them, and they were with the option to return if not satisfied.


They are regarded something different, which is correct. 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. How typical for Ebay. This is great, because the center anode plate is already hotter than the outside anode plate. The next difference I noted, are some costs savings on the shielding. On my tube tester Metrix U61B initially they tested very nice.

Then I let one tube warm up, and apparently it started to reduce plate current slowly. Then they keep just this value no matter how long hours or days I let the tester run. Identical tools are used Another difference is in the part numbering.

What a quality this is! This is one difference.
