The schematic shows the tube filaments wired directly to the power supply. The chassis I am working with has the ground side of the filament power connected together and tied to a rivet to chassis ground. Does the filament power need to be above ground, or is it acceptable to mix the chassis grounds?  Thank you for the help. See attached images.
