Do you have a tube tester? Are you sure about how new your supply of 'NOS' tubes are? If you don't own a tube tester, maybe your NOS tubes are not as new as you think they are.
I haven't heard of the Sonic Frontiers Line 3 being a 'tube eater', but if you're sure your NOS tubes read good before you burn them up, maybe there is something wrong with your Line 3. Possibly bias or something is out of whack. Contact Chris Johnson of the Parts Connexion.
