I am building this speaker protection circuit and just wondered the purpose of R23, R24, R25 and R26 (see attached diagram) and weather i need to include them.
In the instruction manual (see instructions1) it says to include them if:
My amplifier is a non inverting lm3875 with a regulated 18V 0 -18V power supply so i am guessing it doesnt need these resistors since the supply is symmetrical ?
What confuses me is what elcos mean i thought it might mean electrolytic capacitors? but am unsure. Also my amplifier has 2.2uF non polarised capacitors if this makes any difference.
Hope someone can explain
Thanks very much

If the amplifier to which the module is to be connected has a simple power supply (asymmetrical supply) i.e. an amplifier with output elcos, the following resistances has to be mounted...
