Scott, If you pull the SMB lamp connector off of the chassis jack you can Ohm out between the center pin and shield.
Try both polarities of the leads. If the 1330 Ohm resistor is good you should read around 3330 Ohms. This is the sum of the 1330 and a 2000 Ohm resistor. The 12 Ohm (selected) resistor can also open up sometimes.
