Folks, what are the exact substitutes for the above mentioned tubes? Wanna do some rolling on my BAT.
Thanks.
Follow Ups:
IMO Soviet 6922, 6dj8, substitutes etc tubes suck compared to British and Eastern Europe NOS tubes.Try Mullard, Tungsram, Telefunken, and other NOS tubes first.
The Russian tubes are all cold, and analytical sounding IMO.
They are cheap and you get what you pay for.

A representative from Cary Audio once told me, "Tube rolling will make you neurotic."
That was right before he sold me a pair of Bugle Boys 6DJ8s for the front of my amp. (That was Dec. 2017.)
I had just taken that amp out of mothballs, & whatever was in the front of it (I think they were some well used & worn out British Amperexs) I had JUST replaced with some brand new Genalex 6922s (which I then replaced with the Bugle Boys).
Your thread got me interested in doing some back track rolling (nothing as exotic as what you are into) so I took the (almost 3 year old) Bugle Boys out & put the Gold Lions back in last night & spent about 3 hours with them tonight. Definitely punchier bass.
On an aside, for some reason I have a lifetime supply of Sovtec 6922s. Must have been the pair of ARC VTM 120s I had that (I believe) had 3 6922s in the front of each one. Back then I was big into redundancy & spare parts (I guess I still am), so I must have bought all those Sovtecs to support those amps just in case. (& alluding to a prior post I made to your thread, I was wrong, I couldn't find any Sovtec 6DJ8s that I thought I had. I once had a couple of 6DJ8s that came in a CD player; I think they had a red star on them--they must have been Chinese.)
On another aside, when I was searching for those 6DJ8s that I thought I had, I accidentally dropped a tube from one of my 6922 drawers, I think it was one branded Amperex USA (with a cute little red curly design on it). I think that because I found one that meets that description, but just one. I hope they weren't anything special.
what's wrong with USSR made 6H8C?
I put it a 6H9C in my amp, cos I needed one in a hurry in SPB, on a sunday morning.
Shop was open and it was dirt cheap, worked perfectly.
What's not to like?
You won't get that kind of service in the USA.
" what's wrong with USSR made 6H8C?"
I never said they're wrong.
Eric, my amp runs a couple of 6922s up front, & I am always interested in learning more about the subject.
What is the reason for your interest in specifically the Soviet 6922?
Which 6922s are you currently running?
The reason is plain curiosity;), honestly I have too much free time on my hands these days...
Seriously though, I'm just really curious about the Soviet stuff. The tubes of my BAT are mostly Soviet-made or semi-Soviet, so I decided to swap the modern ones with NOS.
I found a guy in Russia, who knows his stuff, he also is an avid DIY-er. He promised to find whatever I want. So far, I have had a really unbelievable experience with the Soviet 6J9P-E tube in one of my preamps, from their first tube factory, and it killed literally every 6688 tube I've ever tried.
Don't remember what's inside my amp (probably new Sovteks), those 6922s are in the bottom of the amp, I have to remove the panel to see it. Once I have the replacements, I'll report my findings about them.
Just as an aside, I had a strong preference for the Voskhod 6n23's.
Your taste in tone may be different, but I preferred the Voskhod in a Counterpoint preamp and as a buffer in a CD player. Reflektor made ones always sounded more sterile/hard to me than the Rockets.
The Tube Store is calling that one "the equivalent to the 6DJ8"?Oops. On edit: that is "Tubes store.com" that is referring to it as such.
(The Voskhod, that is.)The Tubestore.com (which evidently is a different store) is saying:
"The NOS 6H23P-EB (Premium) tube is a very noticeable upgrade over the Sovtek 6922 tube and Electro Harmonix 6922 tube. They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions. They excel in detail, speed, and soundstage. The highs have air and sound natural."Big difference, also, between the prices of the Voskhod at Tubes Store.com & the 6H23 at The Tubestore.com.

Gets a bit confusing when you consider translations from Cyrillic alphabet bet to Latin alphabet, but the 6922 is translated either as 6n23 or 6h23. There are other letters after those, but the "n" and "h" are as close as you can get to the symbol for pi, from Cyrillic, in the Latin alphabet. See at the link below, about half-way down that page, is an explanation of those letters that come after.I've forgotten the Soviet 6SN7 numbering, but as I recall there are two types. The 6H8C (or something close to that) types that pretty much all suck, and then an earlier version (who's number escapes me) with large holes in the plates, that's quite sought after. I've been out of the 6SN7 world for a long time and recollections of that type are sketchy.

Hey Sondek, appreciate the info. I realize how confusing the Cyrillic alphabet could be, but I have no problem with it, I'm fluent in Russian.
So got the numbers. Do you think the one in the picture is good? It's from MELZ. There are even older ones from Foton, but the construction is a bit different.
Wish I could help you, but I moved on from 6SN7s about the time the 1578 was beginning to really get traction with users, and I just don't recall now.
I still love the 6SN7 and 6F8G. However, after I'd drunk directly driven, full-range ESL Kool Aid, I sold the gear I had that used those octals and went a whole other direction.

I bought my first Sovteks in 1989. They've always been a 6922 equivalent. Why even bother to make the lower spec'd 6DJ8? Every amp out there designed for 6DJ8 can run a 6922, but not the other way round. So why would you want to make both types?
Nt
Thanks man, you've been always helpful.
....when I straighten up I can be really belligerent.

Thanks, but I'm looking for the Soviet-made stuff ;)
