Here is a link to the schematic of the AK 30:

The 01 A tubes it uses have a plate current draw of 3 milliamps each according to tube manual. Max plate voltage 135 v.
The 01 A filaments are 5.0 volts DC at .25 amp (250 ma.) each.
It appears to use 6, 01A tubes.
There is also a 71-A tube used as the 2nd AF tube: it has a plate current of 20 milliamps at zero signal. Max plate voltage is 180. Filament voltage is 5.0 volts at .25 amp (250 ma).
Keep in mind that the first digit in the tube number (say 301-a) is a manufacturer's number only and can vary. The real standard designation used in the tube manual does not include that prefix number, and thus is 01-a or 71-a, etc.
