The two capacitors in item 30 a connected from each side of the line cord to chassis ground. This creates a voltage divider, putting one half of the line voltage on the chassis. The current is very low so, it is not a safety issue. The main reason for these capacitors is to provide an RF ground path for the antenna circuit. Think of it this way, if you look at the schematic, imagine a wire connected from the ground symbol on the antenna transformer (item 2) to the ground symbol the item 30 capacitors. As terry said remove the screw from item 30, then check to see if the voltage is gone from the chassis. If the voltage is gone, put the screw back in and don't worry about it anymore.
