Hi,
Congratulation. I can not belief that a simple circuit worked out so good. I forget to mentioned you that can add the second channel to the output of the op amp since the comparators output are an open collector. That will make an OR gate. Any one of the two channel with enable the flip/flop.

Hello Tomas
greetings first of all many thanks for helping me out on this project
its working good all the credit goes to YOU protection is vital for
amplifiers i have tried another short circuit protection at over 1200
watts i am trying to diy a solid state mosfet relay need about 50 Ampere
SSR hoping i can make it
warm regards

Hello everyone!

I take this thread to ask a quick question.
AMB laboratories offers a headphone amplifier for protection but putting a suitable relay the following diagram it may be appropriate for a power amplifier?

Thank you!

Hi,
Did you try the reset button?

Hi,
Did you removed the load? It will not reset until the input current it is normal.
