So, I've been looking at these amazing tubes for some time now, and today I just bought six pieces... Straight from Russia!
18$ is what I had to give. Not bad at all.
I got them on Ebay. There was another offer, 100 tubes for 300$.. I almost hit the button, but sanity caught up with me :D Sadly!!
I love old tech!
