Hello
I like to build a protection for speacker and I have schematic for upc1237 but i dont undrstand about relay.My amp will run on +/-40V Sow what kind of relay should i get and how high should be the resistance in relay to put suitable resistor on pin 6 of upc1237
Thanks

Hi Risto80,
The resistor limits the current into pin 6, max. 80mA. Set this to drop the proper voltage across the relay coil depending on supply voltage. You can boost this rating with a transistor or two. Do you want the PDF? The file is too big to attach it here. PM to bhome_at_sympatico_dot_ca .
