Default lm4702 with one pair of output devices stable with 18pf compensation cap?

Is lm4702 with one 5200 1943 pair stable with 18pf compensation cap?

LM4702 is happier driving Darlingtons or Lateral MOSFETs -- read the data sheets and ap notes.

You better check to make sure this amp is not oscillating at such lower values. I could not stabilize with less than 56pf with those transistors.

The LM4702 can't deliver enough current to drive 2SC5200 -- that's your first problem.

I have tested it with 47pf as single pole and is very stable so im thinking of using 47pf for base compensation and 150pf as second cap for two pole compensation as its 3 times 47pf wat do u say guys?
