I don't know how your testers' configuration controls work. However, if you set the Noval socket up for a 12A_7 and use the electrical parameters for the 5687, you should get reasonably decent results.Both the ECC99 and 5687 are HIGH gm/LOW Rp. Mu of 22 for the ECC99 is greater than that of the 5687's mu.
