Any bare metal conductor between the mains input and the transformer is potentially life-threateningly dangerous. All such connections must be electrically insulated. And mains earth must be securely and directly connected to the metal chassis. Again, this is for safety reasons. All of this should not be taken lightly.

It appears there is NO wire from the ground pin on the IEC inlet to anything? Anyone have a picture of the correct wire up for this?

I am not at home, so can't get a bigger image. But.. if I zoom, nothing to the ground..

pictures are everywhere , if you know what to look for

so - you need to solder proper wire to mid pin of mains IEC and to connect other end to bottom plate - best to solder eyelet on it , then screw to bottom plate

other two eyelets on IEC must be isolated - best with heatshrink , but if already soldered - make that with electrician isolating tape

to avoid hum problems , when amp is connected with (also safety grounded) source , you must have NTC of 10-15R between audio GND ( main gnd point on cap pcb) and case
NTC - search for CL60 ....... lemme try ........ here it is : http://www.ge-mcs.com/download/temperature/920_325a.pdf

after that - spread the word what piece of drek you paid for
