Nice bit of history. Wish I knew more about "upside down" tube layout, as lots of sets like workhorse amps have been chugging along for decades this way.
Seems like the tubes do not care one way or another, but beware of horizontal or angled alignment for types prone to sagging filaments, and so forth.
