    Thanks for the input @123Toid, the 3.4 arrived today.

    I’m going to swap the fan out for a Noctua and also change the old traditional speaker terminals for speakon jacks.

    Have a question, the current speaker terminals are are attached to a little PCB and also grounded to the chassis. Do I need to be concerned about any stored charge zapping me while removing the PCB, and how should I connect the chassis ground to the speakon jacks? I have standard 4 pole (will wire the +1 and -1).
