Shane,

I thoroughly enjoyed viewing your build. I recently build a 300B SET based on "Legacy" C3M penthode input stage. Couple of suggestions you may want to look into to improve the sound.
1] add ultrapath stage. The best source to find out more is from www.tubecad.com site
2] not sure if heard any arching from your power switch when turning it on/off,if that is the case consider adding 0.1uF@400V+ film cap across the switch
3] experiment with 2uF film cap across both cathode caps

Cheers,

Norbert
