Thanks for everyone's kind comments.
This amplifier was built around a transformer set removed from a Harman Kardon TA7000X receiver. The drivers each consist of a 6J32P (EF86) in triode mode driving a hand-selected Telefunken ECC91 (6099 equivalent). Outputs are fixed-bias 6P3S-E. About 20dB of GNFB is applied. The screens of the outputs are fed from main B+ through two 0B2 VR tubes. This reduces screen voltage enough to be compatible with most 6L6 types, including early variants.
Most of the other features that I included are visible in the pics below. If all goes well, I'll do a few more like this in the next year or two.
