These have a larger size bottle, but inside can be anything from a KT88 to a These days are over. For instance Plate Current is between and mA. So you see, how hard this is, and why so many bad Chinese tube stuff is around.

However the beam tetrode did it’s job and the best know family member of this kind is probably the 6L6. The print however is clean, not burned.

Tesla wanted to focus on Transmitter tubes only. As far as I have seen, they write correctly write the country of origin on their boxes.

The people at JJ are clever, and focuses very hard on making a very good KT88, and they succeeded. The inner grids of this beam tetrode can be seen through the end wall of the anode.

You like “another” tube than KT88, well it’s a bit off topic, but try GU Of course you can change the shape by hand. So take it or leave it”. Quality is very good. It is one of the largest tubes in its class and can handle significantly higher plate voltages than similar tubes, up to volts.

Testing of Datasheeet with the L tube tester. It starting with the AL1, the first large output pentode, for radios. The Genelex Power Output tubes in these cartons have been matched to each other on the finest test equipment available. Is the post to blame or the factory? Heater-to-grid shorts, after postage. The ratings are roughly the same as the 6L6GC while the A has higher ratings.

They short in the end, blowing out the amplifier fuses. All I can say is: This makes them very suited for professional sellers that have really good equipment. PART 3 back to contents.

For them this is not screwing, it is giving you what you deserve. Specifically designed for audio amplification, the KT88 has similar ratings to the American which was designed for use as a servo amplifier. Do you believe in this?

From the above paper: To me, the JJ KT88 have the optical impression being made that way. Amazing quality Russian military old stock. The ones I had showed all the typical errors, KT88 can have.

You datasheeet click on the next line picture, it gives a high resolution picture, and you can nicely see the details of the inside piece parts. It has Zirconium coated plates, making the plates act as a getter. In the USA it was the more sloppy 6L6 that won the race.

Here is a typical worn out getter. Also you will see the end of the line is a bit random, which is another sign for artist work. So what leaves the factory is a strange mix of mainly good tubes, with some few bad ones amongst them, no good matching, and not enough burn in. Also the Carbon tubes from Alesa Vaic were a disaster. As you can understand, this made this business not very pleasant to do.
