Cw - well, no - unfortunately, for now I don`t have almost anything of measuring equipments. Without scope you are blind :-).
I mean, ears are not enough - in the last few days I changed so many things and went through many cascode versions...everything is so similar sounding and interactive...
And clever ideas on paper mostly aren`t "good enough" in practice.

6SN7 concertina - I tried it with 27+27k, first stage 56k/620 Ohms. 5687/E182CC concertina - 10+10k, first stage 27k/330 Ohms. I have a plan to change this 27k to CCS in my DIY monoblocs...5687 is a good sounding in many circuits, but I`m little dissapointed with it in the cascode driver...50Vrms out isn`t a joke, though.
If you have a scope and sig. generator - look for the sharp peak around 10Hz - enlarging of coupling caps would probably result in little lower peak, in magnitude and frequency. Keep us posted.
Did you see this - seems interesting PC measurements system?!
