What is this?

ELS122:
The description says : Power block. Block 1
If that is any help

And again I don’t own it so is it worth buying it as it is really cheap and I could use a regulated 12v/rail to rail/tube power supply. I will ask the seller if it’s working.

ELS122:
The seller said that it can be tested, all the fuses are original, the original power cord is still good and hasn’t been lost. So if it works what is it?

soldar:
I am pretty sure it is a power block.

The combination of ICs with string-tied harnesses is ... interesting.

Soviet electronics had a lot of idiosyncrasies like that. It's a weird mix of cutting edge and the past. They made Nixie tubes right up to the collapse as far as I know.

Bud:
Whatever it is, you will need to replace the electrolythics. See if that is worth the trouble.
