Yes, my friends called me that too, but hey, I can't help it, my curiosity on tube amp get the best part of me, plus I can't build enough power amp to power all my 3 tri-amp system. I collect all kind of transformer, just for the 845, I tried about 6 different type (still have them laying around) before picking what I prefer to use now in my amplifier for some particular tube. For the 6C33C, I used James, it turn out to work pretty well on my bench measurement, someday I will post them.
I have long discussion with a friend about DSET with custom transformer 15 years ago, for sure they will easily outperform the the full bandwidth type by a very large margin if you can find a right iron winder. We order some custom build iron to cover high frequency from 1Khz up, and it was a disaster, so we dropped the idea.
This 6C33C was originally planned as DSET, with simply 2 resistors and 2 cap inserted between the input and cathode follower and it will become DSET.
Regarding big transmission tube, for me they are necessary to power 12" - 15" driver even at 99-100db sensitivity with their 20W-25W output.
