Hi Merlin,

Assuming the ground symbols on the schematic are connected to chassis, this radio has a hot chassis design.  Note that one side of the line cord is connected directly to ground through the power switch.

Check how yours is wired -- if one of the connections from the power switch goes to chassis ground, then this is a hot chassis design.

Sometimes the ground symbol on the schematic is not connected to the chassis, and the chassis is connected to this "ground" through a capacitor.  If that is the case on this radio, then a short in that particular capacitor could result in a hot chassis which is disconnected when you remove the connection to the capacitor.

Best regards,

Tom
