The source connection of the MOSFET needs protection from capacitive loads. The small inductance of a wire-wound resistor as shown can provide this, a 0R22 value will do more than 0R1 in that regard. The gate stopper resistors will do better if there is a low pass filter capacitor between the gate and the source. The gate stopper resistors could be increased in value up to 330R and the capacitor value introduced between gate and source, decided by trial and error. This circuit looks tidier for stability as there is only one capacitor around Q4 however the value might need to be changed. This could be connected from the collector of Q4 to the base of Q2 as has been indicated in another input suggestion. I would not recommend a lead capacitor in parallel with the feedback resistor as any hf instability due to the load will be introduced to the system
