I spent some time looking for Spice models for the the GU50.
I managed to find some Russian tube models here, including the GU50: audioportal.su/showthread.php?t=7020
I am however not able to get the models to work in LtSpice.
It seems the tetrode/pentode models have the electrodes in a different order than the LtSpice symbols from DuncanAmps, and I do not know how to fix this.
More strange; the triode models seem to have the pins in the right sequence, but they do not work either.

Update:
The triode model works.
Must have been a "hick-up" in LtSpice that showed wrong current, in the wrong direction through R2. Deleted and re-inserted resistors and it works.
For the pentode I have temporarily defined a new symbol with nodes in same order as the model.

I did not log on and download the files stored on the forum, but I did a little bit of Internet Archeology;
I tried to follow a link to to a page which was no longer existing, but archive.org had a copy.
With the added help of Google translate we get this page: Next-Tube. Design of vacuum tube audio amplifiers
Here we find the PSlib.zip file that I attached to in post#1.
There is also a file Tube_ORCAD.zip that has a larger library which also include the 6E5P

revintage:
To create a symbol to work with the models in tubes_IM.inc, just open the existing tetrode symbol and edit the pin number assignment so that
P G1 C G2 correspond to 1 2 3 4. Make it look a little different, and save it under a different name.
Attached is the symbol I used (tetrode-Ry.asy)

Thanks Svein!
Got the files and the triode models are fine. The only tetrod I tried was the 6E5P and I keep getting the error below. I tried reworking both the model and the symbol and keep getting this result. I'll try with the GU-50 to see I I can replicate your results.

I found that the pages of Eugene Karpov that I linked to in post#4 are available and active at a new address, and in English language, so no need to use archive and translate.
Next-Tube. Design of vacuum tube audio amplifiers.
Lots of good stuff there.
Dave,
the error message you posted is typical if you use a triode symbol (3 pins) and a spice model value for tetrode (4 pins)

I have ordered some tubes for my Peach from Tubes-Store.com - Vacuum tubes, capacitors, nixie, sockets. Wholesale & retail trade. Worldwide shipping.
and good info about soviet tubes is here Next-Tube. Vacuum tubes and cores datasheets
