Looks like a 25KV anode voltage. Probably a knock off of some early RCA tube.
This set is very neat, never knew it existed. I really like the styling of the cabinet and especially the screen.
I would be very cautious to actually use this TV, it's operating at or close to 25KV and I doubt much effort was put into
containing x-ray radiation! Maybe I am wrong, but I wouldn't take that chance.
The name of the set translates literally to Moscow, from Moscow Television Plant, model is from 1957
