Not really a 6SN7, but does anyone have a resource to find out whether a Mullard ECC32* is a russian replica?

A pair was offered from a local reputable shop, but I didn't immediately buy it because I don't know how to identify it, I want to ensure I don't make a mistake

They look ECC32 to me as well. Just a tip..next time, take picture of the interior, especially the plates as well as the top mica beside the front picture of the whole tube. It will help a lot for verification. Lastly, in general, Mullard ECC31 n ECC32 has the following getter ranging from the oldest to the latest as such...
Pan / Tray -> D -> Rectangle

I will take note of that, thank you for your expertise.

The seller also sent me the date codes of 1185 EO and GO

My understanding is that the Russian copy’s have a shiny plastic base, and the domed top is a little larger than genuine tubes. Probably difficult to spot, especially in photos.

1185 is the early code for ECC32
2 or 3 characters date code (pre 1960), 4 characters (post 1960)
A - Jan, B - Feb......
0 - 1950, 1 - 1951...
Later code for ECC32 is EN*, * is the change code
In case anyone is wondering, not all ECC31 or ECC32 are made in Blackburn, I have ECC31s from Mitcham (D) as well as Blackburn (DA). Also, I have seen ECC32 from Blackburn and Mitcham.

Do you have any of the 1578's from the 1950's left?

I have quite a lot and may be shifting from 6SN7 with a custom 300B amp.

Thank you guys for the help, these sound incredible.

There is still a shipment from Ukraine for a pair of youknowwhat, but I think I am done with driver tube rolling for now, hopefully I won't annoy anyone else with my newbie questions again in this thread for abit (unless god forbid that pair of 1578 needs some resoldering...keeping my fingers crossed). Maybe 1 pair of 300b next.

Thanks to everyone for the guidance over the past few weeks!

Congrats! Remind me it's time to switch the B65 to ECC32 on my WA22 again!

I would definitely be interested in helping you with the transition when you sell of your MELZ 1578, please give us a heads up here or PM me if you would be so kind!

Got the Visseaux 11n7 in and... I'm having the same problem I do with the ecc31. Weird, phasey sound with an exaggerated midrange. My amp just does not like those tubes. It bums me out cause people seem to love them. Fingers crossed, my amp coming later in the year won't have the same problem.

Hey folks, does anyone have any experience with the seller oak-man1 on eBay? I'm a noob to buying tubes on eBay and don't have any testing equipment to ensure the tubes don't make my amp explode

Any help is appreciated

Not familiar with oak-man maybe others are - curious what you might be looking for if you don't mind sharing a bit more ?

Doesn't look like a tube seller. Rather a guy that sells tubes along with a bunch of other stuff. Dunno what that means for his tubes.

Well after several years I am back in the game. I picked up a Lyr 3 again and will be looking for 5sn7 and the like tubes again. really wish I didnt sell my tubes when I sold my lyr 3 several years ago as tubes seem to have skyrocketed.
