I smashed one PZGRL F80T12 to see what the hell was happening with it. It was NOS, but it didn't start on preheat nor on electronic ballast. The filaments glow like normal, but only in orange, no discharge took place. I checked with IS ballast and when I touched the glass with the wire it glow like normal tube, but the cathodes were not working. I decided to smash it open and I saw that the filaments in a NOS tube were sealed into the tube with no emitter on them! That's a true PZGRL quality guys.

Thats a pretty sharp photo. You can nicely see the triple coil with oval cross-section, and internal basket wire to grip the emitter. If it is present! I wonder how many they made before realising the emitter had run out.

Ha! That's a good question actually. Presumably, the soviet quality control, the one sober guy that shows up to work at least once a week checked in the morning, saw that the emitter coating tank was empty, was too lazy to call for a fill, and just let the machine run. He napped in his little cozy backroom for a few hours, then woke up at noon, and decided to replenish the emitter tank before a thousand tubes went up for sale. The guy just recalled the already made tubes as 'defective ones' and trashed them or just send them up for packaging or whatever he could have done, just to lay the work from his ass. That's the soviet quality control. You'll be surprised to see how many defective 'new' things came out from factories, because there was a single step in the manufacturing process that was absent to save time and money - testing the final product. All eletrical things like kitchen appliencess, radios, tvs, etc. were sent to the market while being defective. The tubes were not an exception. They were rarely tested in the factories, and any defective tubes in the majority of the good ones were packed together and noone cared enough to be bothered about it. It's like in that one joke everyone knows in Slavic countries: The guy comes to work at the meat factory. He comes to the meat extruders and bangs the machinery with the metal pipe so all the rats and mice could run out, so the sausages wouldn't have rat meat in them. Then they switched on the sausage machine when all rats ran out The sad truth is that this was actual things that happened in soviet factories.

I actually seen in my tradeschool lamp graveyard in the basement that I cleaned up, many soviet boxes of tubes branded SLZ, LISMA, RAZNO, etc, and they had unused tubes in them, in their sleeves, seemingly unused. They were defective straight out from the box and were just left there to be thrown out. In 7 boxes of 30 tubes I saw had about 5 to 8 tubes as 'defective'. Cool, heh? I even heard somewhere that brush DC motors in vacuum cleaners "Saturnas" and "Raketa" were sometimes made and assembled with the brushes absent from the motors.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.

Yes, when you finished your education in whatever profession they prescribed to you (You had no freedom to fulfill your dream jobs, when you finished high school, you were given a random paper that said you have to go to university and your future job will be: Kindergarten teacher) you then got a job, guaranteed for life, and no matter how bad of a job you did there, you still remained in that cozy seat of yours and you got paid no matter how good or how bad you were.
