AK35 uses 6 - 01A's. Original version would have been marked UX201A or CX301A. These are globe shaped with prefix identifing manufacturer. Later the prefix was dropped and changed to ST shape.

Other tubes such as 112A and 71A for output can be used.

Believe you are not in the US? If 01A's are hard to find you can use #30 tubes in an AK35 by reducing filament to 2 volts.
