Crickets chirping indeed. I am almost afraid to ask. Anyway, Lon said it well when he advised hunkering down for the long wait. On the other hand, I did not heed his very sound advice to order the Ultra with tubes. And it is sound advice. But.......... I kept my order tubeless and ordered a full cryo'ed set of
these National NOS tubes. And of course, a variety of 0A3s and alternatives, a Mullard GZ37 and some other rectifier alternatives, to go along with some very nice NOS Sylvania, Mullard, and SED Winged C I already have. See, this is how I am keeping myself from gnawing off any more extremities in anticipation.

I will build a little worksheet of tube combinations to start with for the Ultra and the Toriis, break them in, make notes, and then attempt to exercise some self-discipline as I listen, live with each combo for a while, and record impressions.
I also ended up getting two ZRACKs of the taller size that Steve recommended.
