Hi, has anyone tried replacing the 12V power supply with a 24V supply? Also the desirability of adding a second mosfet?

Second mosfet for?

MORE POWER!!!

You can add FETs in parallel to get more power or less losses.
Only caveat is to make sure you have enough power to drive the gates.

These days it comes down to a thermal management issue.

Why not add a 120V bed with dedicated Mosfet and controller at a total of about $50 and not mess with the PCB and the gate controllers?
