Performance triodes, made in Russia

This page is dedicated to my favorite tubes, my declared favorites, they all come from Russia.
They are all power triodes, triodes which are mostly manufactured as linear regulating tubes for power supplies, but are now very popular high-end output stage tubes for many.

The following photo is one of a whole series that I created, and of which I would like to show each of them in the first place - which of course forbids itself due to loading times. Instead, the first, the following image, is also the link to a page that shows all of these photos. (And I am free from the decision to choose just one - and not be able to show all of the others ..)
