Used lytic 220uF as Vref & lytic 47uF for Zobel without R but jumpered as per SSLV1.1 BiB guide
What do you want?
to change Zobel Lytic
to add 100uF lytic across sense+ & sense-
Can I use non polar?

First add 100uF across sense as it is. Non polar is OK. Then try Zobel MKT+R in case its still fuzzy if that lytic now there has a problem. But leave the one across sense.
Still problematic.
Merlin, do you have 270R for sure in gate stopper place (parallel on board near the input & output Mosfet pins)? Or something different value by any mistake? Some used before heated cap many times with iron? Because you should have simple line like in your positive pic no problem at least with dummy test.

That's the proper line, even on real active circuit load.
What was the vertical (volt/div) knob's position George?

Measured all four gate resistors 270R in the negative rail and all four measure 270R, attached pic right channel negative rail

Looks typical except for rather long Mosfet legs. Still something wrong is going on either parasitic or component wise. Put 1R instead of jumper to see what it responds to us. If still fuzzy, then C204 MKT.
Transistors, Jfets, inspected for proper type proper place odd mistake too?
