After exploring every Voskhod Rocket I could find - and all the common Reflektor 6n23p dual getter posts from the '60's and 70's - I stumbled on a very rare Reflektor version with a single curved wire getter post. I was floored at how good these were - and only found ones made in '74 and '75.

Followed by a June 2014 face off with some of the outstanding US and Euro tubes post #2229
That had me curious as to how the best 6n23p's would compare with the finest 6922's ever made and the big review:
Jude awarded me a front page kudo and Contributor status (And added it to my header).
I hope this helps those wanting to explore these amazing tubes and possibly help answer any questions folks have about them.
Cheers and Happy Rolling!
