6922 Sovtek Variances ???


The earlier 6922 Sovteks look exactly like a Svetlana 6H23P-EB, I have both in my hands and they are identical, right down to the O getter halo. The newer Sovteks are not similar at all, they have a totally different getter halo? What gives? Can anyone shed some light on these findings?

Thanks

I suggest you try and save all thoes old Sovteks, one day they will be the hard to find, costley, much sought after, N.O.S............of the next generation. Ha
At last, a grrreat use for those old Sovteks. I can save them for future resale. Who'd a thunk! At last a perfect solution. Are used pulls going to be valuable too? :-)
Look at the trend. These Sovteks will one day be worth over $100 each! I have these Russian 6H23N-EB tubes that I bought of eBay many years ago for cheap. Now they are called "Premium NOS Russian military tubes".

Slates:
"Plates" is that lower 1/3 section of the tube structure. Kind of look like a rib cage.
