I tried already various 6922, 6N1P and 12AX7 in the same socket, without any changes and without any problems. I guess it depends on the specs of the system, so if your specs are in an acceptable range for each tube type you can give it a try.Ralf
***I tried already various 6922, 6N1P and 12AX7 in the same socket, without any changes and without any problemsWithout even changing the heater voltage? Hm...
There is no harm in doing this, anyway. As long as you don't put kerosene in your car and gas into your kerosene heater.

*** Without even changing the heater voltage? Hm...If the heater voltage is 6,3 Volt and the circuit can deliver enough current for the 6N1P ...
The main issue are the results in fidelity, and it is clear that the amplification factor of a 6922 and a 12AX7 is different.Ralf

There's an easier method of trying 6N1, and it's an NOS sub:
6BQ7, 6BZ7, or 6BS8. Electrically almost identical to 6N1,
certainly close enough to sub, and cheap, too.
Just pull 'em out of the front end of yer tuner & try 'em...

I am not sure I understand your question, but the 6N1P is not a substitute for 6922, no matter what Svetlana tells people. It is a totally different tube. It has the same pinout.... true.Victor.
Hi Victor,What do you know about the 6N23N-EV?
I understand LAMM uses them instead of 6922s.
***Hi Victor,

The 6N23P-EV *IS* the Russian 6922. I presume LAMM further selects them as per their criteria.Victor.
It would appear to be from a different factory than the 6922 Sovtek sells (or made to a different spec) as it's internal physical construction is quite different in terms of plate structure....Joe
***It would appear to be from a different factory than the 6922 Sovtek sells (or made to a different spec) as it's internal physical construction is quite different in terms of plate structure....The 6H23 tube used to be made at several factories. Today I believe only the Reflector continues making it. But regerdless of where it was made, it must meet the same specs, even if the internal structure is somewhat different. There were two versions: 6H23P and the -EV one, with slightly different specs. What we get today through New Sensor is the -EV version (at least we all hope so), because that is the version that is crossed to the 6922 type.
I don't want to appear that I am speaking for Vladimir, I am simply saying what I understand it is. You might want to ask him that question as well. As I stated before, I do not know his selection criteria.

Victor.
I recently got in some late 1970's early 1980's 6N23n-EB. I think that most of these have been sold by New sensor over the years. I have seen a few different types. Some with upside down dish getter, some with a circular getter, some with grey plates, some with silver. Plates themselves, pins, bottle, etc always look like they came fom the same place.But one customer who has had all three feels they sound quite different. I have not had time to do evaluations myself. Perhaps later. But getting an exact description as to plate color and getter is tough when you are importing a tube that is not too expensive. I may try to get some in that are nifty.

Plates themselves, pins, bottle, etc always look like they came fom the same place.Also, tubes produced at the same factory would undergo many changes over the years. The Soviet factories used to be swarming with pests called "rationalisators". Those usually were production workers who believed they could design things far better than engineers. So as soon as designers would leave the production floor, the pests would crawl in and start making "improvements" to the product. This practice was highly supported by management and the Party apparatchics, for it meant showing the decadent "specialists" what a dumb "proletarian" could do if equipped with nothing more than just a revolutionary zeal.
Many fine products were ruined by those pesky rationalisators. All good engineers hated them. My former boss used to say that all of them should be taken outside and summarily executed on a sunny day.
So, if you can, get the tubes designed by engineers, not the ones that have been "improved" by the rationalisators. How do you tell them apart? Damn if I know.

the word "specialist." Many nurses, who are quite capable in their
own right, start believing they can do it better. Then the patient
dies. Uh Oh.Chris Garrett
no, a 6DJ8/6922 cannot be substituted with 12AX7's or any of it's variants.use the link below to check for yourself, then bookmark it.
