Have you tried the 6N1P (6H1N-EB) Russian Rocket as a variant to the 6N23P? When I got my LP-2, previously owned, I decided to replace all the tubes. My LP-2 is an older model with 6922 type driver tubes. Anyway, I bit into the more $$$ is better at the time and got a pair of Bugle Boys and swapped them in and never looked back. A couple weeks ago I had a bit of noise coming in one channel and while trouble shooting the problem I put the 6H1Ns (Dennis supplied these originally with the LP-2) back in and WOW! I do not recall the source of the noise now but either way I have not even thought about rolling the Amperex back in. I did go for broke and rolled a 6H1N in place of the Bugle Boy in my amp but what ever the improvement was to the sound before was not enhanced further at this later stage of sound processing. As I research these Volkhod tubes I see that some of the vintage 6N23P tubes from the height of the Cold War have additional value in $$. What are your thoughts on the sound? At this point I am not looking for minor improvements but more to collect a few backups of my favorites before all NOS get to WE prices. Have you tried both the 6H1N and 6N23P for comparison?
By the way, Thank you as well Florida Boy for the 6AR6 and 6K6 suggestions. Very happy trying inexpensive tubes that sound great.

Scott,
Not in a while (6N1P). IIRC, it was this tube Dennis supplied as the driver in my amp, though a current production one. I did try Voskhods and still have one. I can swap it in and see what it sounds like to me today (though I have new Omega speakers coming tomorrow and might be a bit preoccupied! :)). I went though my typical too long list of candidates and settled on the 6N23P. I've tried some of my previous drivers here and there, but keep coming back to this one.
I do have a couple of 1975 Voskhod gray shield, single wire getter post variants. These are supposedly the best along with the 1974 Reflecktor silver shields. I'm not sure there is much difference between that particular year and design compared to others around that time, but all were pretty inexpensive ordering from the Ukraine (like $20 vs $40) and I believe that there is nothing wrong with placebo.
It seems to me that the origin of this "holy grail" 6N23P was completely due to one person's review. He claims an extensive listening test with a dozen or more of this tube family with a spreadsheet of various criteria and systematic rating scale. But, he also sells these tubes with the ones he rated highest carrying a significant premium (sells them for $100+ each), so who really knows given the potential conflict of interest.
Florida Boy gets all the credit for introducing the 6AR6 and 6K6 tubes here. I also checked them out and now endorse both the 6K6 - I like the 1950's RCA's at less than $25/pair - and 5Z4 rectifiers - either the Brimar 5Z4G ST style or the very early RCA 5Z4 metal body. The Brimars are about $50, but the RCA metal is under $20.
It is amazing to me that, after spending way too much on tubes, some in the 100's of dollars, that my amp has power tubes that cost less than $25/pair, a driver that was $40 and a rectifier that was $15!
My LP-2 takes that obscure 6FM7 ($2 each!) and a rectifier. That rectifier is the most expensive tube I now have running - current production Sophia 274B. I'm kinda glad that my LP-2 doesn't take 6922's or my life would have been even more complicated and expensive (would be three each of whatever tubes I would have wanted to try).
