I am a newbie on Lt spice ,I DL https://www.diyaudio.com/forums/tubes-valves/243950-vacuum-tube-spice-models-post3662623.html
and put it in a folder "tube" in lib/sym.
But when I start the program and go in to component threres no tubes there...
And how do I Import this? https://www.diyaudio.com/forums/tubes-valves/45287-jj-tesla-ecc99-spice-model-post510011.html

It's hard to know where to start...
First, you want the Ayumi_LTspice.zip file, which contains SPICE models for a number of tubes in a format compatible with LTspice. These will need to be extracted from the ZIP archive before they can be used. But you should place them under the "lib\sub" folder instead of the "lib\sym" folder. The "sym" folder is for symbols, and the "sub" folder is for subcircuits and library files.
The Ayumi models have to be used with a symbol file. Fortunately, LTspice has built-in tube symbols; these are in the symbol [Misc] folder. For "pentode" models you need to use the tetrode symbol rather than the pentode symbol, since most "pentode" models do not model the suppressor grid; that is, they are actually modeled as tetrodes.
The JJ Tesla ECC99 model that you linked is incompatible with LTspice. I've converted it to the format that LTspice expects and have attached it here.
Finally, you need to "include" the SPICE model in the schematic so that LTspice can find it. Attached is a simple schematic that illustrates the process. The include statement assumes that the model file ECC99_JJ.txt has been stored in the lib\sub\tube folder.
Good luck.

Hmm I placed the schematic file and the txt file you attached in a folder sub/tube,and I can open the schema of Ecc99 but when I press run It says it cannot find the txt file.
And more basic how do I open the "build in" tubes When I look in Components tube it´s nothing there..

I have copied these posts to the main LT thread where it will get more attention. Post #2731 onward.
Installing and using LTspice IV (now including LTXVII). From beginner to advanced.
