Default NOS 6P3S-e or cheap new 5881? Identify this tube..

The getter is different from all the 6n3c-e ( 6p3s-e). Are they blank Groove tubes... Sovtec?? Nothing on them, blank bulb... I've post last week about them... I've look all over the place, the getter is a small ring ( normally, on 6p3s-e, it is 2 small rings... Any help???

I think this is more than obvious or even disapointing (original price vs. brand)
but at the end the russian ones are ways better than common chinesse ones
Happy holidays

@banaca: you're right, I could not find such a getter among the tenths of 6P3S-E from my own stock.
But the remaining part of the tube seems to be really similar.
Your tubes are probably 5881, as illustrated in matonOO's picture.

Yes they are 5881 .. got them at a good price. They are blank tubes made by the Reflector plan. I did got some 6n3c-e last week from Jim McShane , a good re-seller in the USA

they apear to be common or normal 6P3S-E but reflektor rebrands them like 5881
Itīs pure comercial rebranding, in the insides there is a russian 6p3s
just keep the dissipation below 20 watts per tube and the screen below 350v

I've pushed them to 24watts, but kept the screens below 350....
sound great into 6.6kRaa outputs, run out of steam into 4.3k outputs
