The protect should only kick in at short circuit,, it's not SOA protection, therefore should be fine for your MJL21194s.
Thanks Vostro, just curious about apex protect because if i'm not wrong he ever said it's include over current protection, that's why i ask does changing the final transistor affecting to overcurrent protection, but i'm newbie corious to know what is the pro circuit send to the protect kit? that's my 2nd question :eek: sorry OOT n my bad english
