Someone pointed me to this thread as the PSU5 replacement boards always produce a bad audio fart on power down.

Is this re-inventing the wheel?

There used to be No-pop relay boards that were wired into the speaker lines and I believe powered by the sound board voltage.
They sell them on ebay for around $5 each
