The clock comes with tubes that may not display some digits. An effect is not visible because the first tube needs to display only 0,1,2,3.
And third tube displays only 0,1,2,3,4,5. I have tubes where "4" and "7" are not working - the first tube will be placed in the first place in the clock and second to the third. To the second and fourth place will be placed NEW and Fully functional tubes.
