Not looking for anything too expensive because this is just for my setup in the bar, but the one I have now started getting a nasty hum. It’s not groud loop because if I tap on the sub it goes away for a short time.

Let me know if you’ve got something collecting dust you want to get rid of.

Nevermind. I got bored and took it apart. Turns out the hum was a loose transformer. Slapped some old exhaust gasket between it and the chassis, tighted the bolts, no more hum.
