HEre is an amazing sounding small OTL amp utilizing four 6H13/6DJ8 and four 6H23/6AS7 a la Atma-Sphere. THe sound is more similar to every other OTL I've had (Transcendent, Atma-Sphere, Berning...) though I would put this one's flavor as a little more SET-like. It may possibly be it's low-ish power rating, but it does not strike me as incisive as some, or as bright/tipped-up as others. The clarity is still there, though. And where else are you gonna find an OTL for this price?
There is a volume pot in there but it has been taken out. Cosmetically in very good condition, though never was perfect due to a certain DIY aesthetic. Unfortunately, I can't remember who built it or any details aside from the power rating. Oh, and it's self-biased so no need to ever mess with it. It's very plug and play and has been extremely reliable. If you are in, or find yourself near, NYC you are welcome to come have a listen in Zyx Universe/Triplanar/VPI/MP-1 system over either Phy open baffles, Lamhorns or CAR T-3's. The Lamhorns with this amp were a particularly good match.
I'll cover domestic insured ground if you can mark paypal as "personal" so there's no fee (or feel free to add 3%). MO and check are also fine.
I always overpack with plenty of bubblewrap, styrofoam, big box...
