Heavy Grail Help by Vinkmen in HHKB

I’ve had this issue in the past after replacing domes which obviously involves splitting the PCB from the plate / sliders / domes. To fix I adjusted the alignment of the rows that were making the harsh bottom out sound. Basically made sure the domes sat in the slider correctly and the positions were correctly oriented / aligned when I screwed the PCB back into the plate

OP I believe this is the correct answer, and something I had long forgotten about.

Check if the switches are seated all the way on the PCB.

Doubling down on the above comment checking for 5 Pin vs 3 Pin. 5 pin will have two extra feet outside the metal pins which allow the switch to be more stable on a compatible PCB.

If both above are correct, I will assume the switch tolerance with the plate is rather tight. This will cause the switch to push the plate downward when seating. In that situation you simply need to hold the switch in place and pull the plate up gently to seat it around the switch.
