What else can I do? I can't mount these things above the chassis...shock hazard...

Okay, guys: Can the circuit be redesigned to use Zeners instead of resistors? And if so, will there still be a major heat factor, or not?

I am definitely not comfortable with the amount of heat these things are generating, and then that chassis sitting on the bottom of the wooden cabinet (even though the cabinet has slots for a modicum of ventilation).
