okay,here is how I've wired the E12:

20 MOhm between my G1 and G2... 
Could have been wise to name G1 and G1' if there behave differently, don't you think?
(at least for dummy M3 builder as me...)
Measured 0 ohms between ε12's outputs and the appropriate plug contacts: OL -> tip, OR -> ring, G2 -> sleeve
