Hello. I put a pair of mono speaker protection circuits inside the amp using the 12VAC BE lines as power supply. It works great. Be careful, to use the BE lines the modules must have floating ground.

Hey!

That looks like a nice easy implementation. What is the circuit? Nice to utilize the local power supply.
