Using speaker protector with high-power amp

摘要

Can the Loudspeaker Protector (October 2011; siliconchip.com.au/ Article/1178: Altronics kit K5167) be adapted for use in amplifiers with higher power ratings than the 135W amplifier it was designed for? (J. S., Thirroul, NSW) We give resistor values in the circuit diagram on page 35 for supply rails of up to 70V That implies it can be used in amplifiers that can deliver up to about 400W.
