re-post schematic you are using , post plenty of pictures
silver mica is good , but ceramic is good also .......... so - unless you already have silver mica , don't waste money on it
however ..... these few questions I already answered
(OK , once more - 500mV across 1R source resistor)
10pF cap , in feedback net , that one is preferable to be silver mica

see edited schematic
changes marked with red dots - change two resistor values and add two additional multiturn trimpots
during setup procedure - both inputs shorted to gnd , no load at output
you have 370mV instead of 500mV across source resistor ( so decreased Iq) - simply slightly different batch of mosfets than Papa was using
that's normal thing
anyway - matched output mosfets are absolute must !!
