So I have this protection circuit from some time ago that I built from Apex schematic. I decided to add mosfet output instead of relay. I want to add also a thyristor output clamp so that after the MOSFET turn off the current from the speaker coil and filter doesn't cause spike in the output. So to short circuit the output after relay shuts off.
The idea is to use a thyristor in series with a 16ohm or some other low value resistor for safety so that in case the thyristor closes during amplifier operation the output isn't shorted but instead simply provided a load.
I have attached the schematic where you can see the mosfet output and a ground symbol. What would be your ideas for a circuit that would switch on a thyristor when the output relay shuts off?
