Really nice long exposure camera shots! Love the thermionic glow!
Yup, you got it, output impedance should be somewhere in that range
I'm a big fan of the 6N6P as drivers as well. They are usually dead silent on pretty well every amp especially when they have their sections paralleled in 6N6P to 6J5 adapters.
Sticking with the Melz 6N1P, I swapped the power tubes to a pair of Tung-Sol 7802. Despite looking very similar to the Tung-Sol 6080 (there are subtle differences), these have nearly 3x the transconductance of the 6080 (20,000 vs 7,000 µmhos). If my math is correct (@A2029 keep me honest) a pair of these run the amp at about ~28-30 ohm output impedance.

Sticking with the 7802, I swapped in the Foton 6N6P. This is simply awesome. The grip, clarity, layering, microdetail, texture, slam - it's all there. Defying logic, there's ALSO a greater sense of smoothness, fludity, and slight decay that's absolutely ear melting. The sound manages to stay totally coherent without falling apart from diffusion.
