Measuring direct on the emitter of Q35 (10mOhm scope) shows 10V DC offset and 300mV raw noise even here (before being subject to any gain). Suggestions? So I swapped out the 2sc828 for another small sign...

I've tried the original (Yocto) circuit with R127 of 4K7 and ended up with a minimum of 420mV noise. (Measured on Fluke 87V and 10M 2445B Tektronix scope) I've tried increasing R127 to...
