schematic or tube list for National NC-105
 

Ive got a National NC-105 and need the tube list,

It has 3 12v tubes in it that i suspect should be 6volt

I know some nationals had both 12 and 6 volts,but the size of this transformer makes me think it should be 6,and it hardly lights those 3 tubes.

any help would be appreciated
