RE: 6SN7 circuit

The 6SN7 is a linearity champion. There's more than 1 good way to exploit that linearity.

The cathode coupled (LTP) hybrid design I'm uploading is non-inverting and comparatively low gain. Given today's 2 VRMS digital sources, lowish gain is a definite plus. The O/P impedance of the setup is below 100 Ω, without resorting to costly step down transformers.
