Sorry, my brain needed more coffee. An audio amplifier that processes

I choose tinned copper rather than diecast boxes as 55020 specifies
dimensions for the boxes. I proved them using a network and spectrum
analyser. Some of them complied with the spec of the standard as built
others required tweaking. I remember the hardest one to get in spec was the
