diyAB Amp  The "Honey Badger" build thread
in my amps, safety ground is connected to the nearest netalwork, i.e. in one of the screws holding the IEC socket screws...

i do not connect the main star grounding of the psu direct to chassis, but where the signal is lowest, via the input jacks and thru a low ohm resistor....

i have done amps using plastic casings, and grounding was never an issue...

This design already has a hum breaking resistor (HBR) R4 and some diodes between power and input ground. My concern connecting the input ground to chassis would be safety.

Hi Stu, they are the transistor mounting screw heads seen through holes in the PCB. All the transistors mount underneath the PCB to save heatsink realestate.
