Default ocp

Andrew OCP Detex same the Crest class D amps ,Lm311 and 555 ,triell ,more simple a npn transistor and 555 two work fine ,a lot similar protecction on class d amps you only parallel 3 X1 ohms 5w resistor paraleel , and adjust the trimp to the desired humbrall protecttion,(sorry my poor english) more efficient + and - v sense ,another way old AB amps like Peavey the shunt sense resistor to gnd series to the speaker,y share schemm soon..

Hi Exflaco

warm regards
andrew
