More pic.

Another pic that might be of some interest.

As a comparison, the picture shows Sylvania 7591A, 7591AEH and 7868EH side by side. I didn't angle the tubes right to show the plate structure differences, but 7868 is closer to Sylvania 7591 than 7591EH. 7868EH doesn't have the same guts as the 7591AEH.

7591AEH has been indestructible. Hopefully the 7868EH will be that way too. The sets we got will be going through some heavy duty abuse. I'll have some real data in a few weeks if anyone's interested.
