Anthony,
  
I feel that 18AWG is a bit too weak for the filaments. I usually use 12. I do not know if you allow to have any ventilation around the 6C33C, I did. In my full range amp, I had holes around the 6C33 panel.

The 6-Ch version with 3x6c33 has the same holes a cooling fan

Yes, certainly the Teflon insulation will help but generally you should have some kind of outlet for hot air outside of the chassis. I typically follow the rule that the temperature on a sealed tube amp inside after a few hours of operation should be comfortable for my hand.
