we've been through this 'linearity contest' before, here.
whereas you define it in terms of current amplification,
i define it in terms of voltage amplification.
as real-world interfacing in audio is with *voltages*,
doesn't seem unreasonable...

excusez for not having included you on the ss

so, why not build flipper's frontend , completed with that
Toshiba 2SC5200 for power
& report back ?
