Hi there!
Today I found a TLD 30W/34 DE LUXE tube. It is used, but still works fine. I think it was in a fixture with stuck starter because of the end-blackening on both electrodes. I let it burn today for about five hours and much of the blackening disappeared. Datecode is 5D which transfers it to April of 1975. It has the tiny Philips etch where the letters are very small. Also it has crimped endcaps with soldered pins, made in Holland.
I know this is an old post in the forum, but I will let you know that such a tube exists
Best regards, Marc
