Since we're showing off our tube amps.....
My Airmid OTL, designed and built by Keenan. It's one of six in the world, one of which seems to be lost forever, unfortunately.
I call mine The Yeti, for obvious reasons. It is one of two to have dual mono volume, making finding matched tube pairs, slightly less important.
This amp takes a pair of 6C5s or 6J5s, which are one half of a 6SN7, and for whatever reason sound distinctly better than their 6SN7 counterparts.
In the rear the Yeti can take a pair of 6AS7G, 6080, 5998, 7802, etc...
