If the antenna coil is open, this may also be the reason for the ability to pick up the same station on 2 different points on the dial, especially if the wire antenna directly on the tube cap is used and the secondary of the antenna coil or the band switch (located on the rear apron of the chassis) is also open.

Please note that the antenna connects to the primary of the antenna coil through a capacitor and there is no ground connection as is traditionally found on sets that do not have an internal loop antenna.  This is because this is a "hot chassis" transformerless set.  Usually on later AC-DC sets, the chassis was connected to the power line, heater string "A" return and B- through a cap or cap and resistor.  However, on this set, the chassis is directly connected to power.    Worse yet, the power switch is between the chassis and one leg of the power line, making the chassis, control shafts and any screws protruding from the bottom of the cabinet electrically "HOT" if this leg is connected to the hot leg of power and the switch is on or if this leg is connected to neutral and the power switch is off, making the chassis hot through the heater string which is a very low resistance when the heaters are cold.  This makes for the strong possibility of a dangerous or fatal shock!  (At our age, the tickers are not as strong as when we were stupid kids.)  I strongly suggest using a polarized plug on this set and rewire the set so that the switch is on the hot side and the chassis is directly connected to neutral.  This may or may not increase the hum level depending on how well the switch and volume control are shielded, but it WILL make the set safer.
