My N5X^2-mk2 (more like a hybrid L2L/Super eXtreme/UHG) build scope traces

Channel 2 is reading from 1st grid. The reading is inverted where appropriate (shown by pink trace). Input signal is 1Vpp, 500Hz.
G1 is a dual gang pot, so the setting from L2L -> Super eXtreme mode switches from one gang to the other.
Condition 1 - G1 and G2 at 50%/noon, all other pots at 50%
Ch 1 L2L-style Feedback mode Super eXtreme / UHG mode
