Put the old tubes back in and try again. Despite the mystique of NOS tubes, your chances of getting crap are pretty high. Even if they were tested on a tube tester, once in circuit, with the higher voltages and currents a lot of tubes don't run properly.
If it runs with the old tubes, you've bought some clunkers. Also make sure they are the right tubes.
