Welcome to the phorum, Steve.  Your neck of the woods is on my bucket list to visit...someday.  In answer to your much earlier question about converting to a three wire line cord, yes, with this set you can connect the ground to chassis.  This is evident in your photo by the riveted ground clip on the back of the chassis to the right of the insulated antenna clip.  This is not always the case, but since it was intended to have a ground wire to earth you are really not changing anything.  The only possible disadvantage is that by grounding to the home wiring you could pick up "noise" from other equipment and appliances tied into the same ground network.  Take care, Gary
