Check to make sure that you do not have a direct short with the wires leading to the Tube. Also, check the terminals of the amplifier to make sure one wire is not touching both terminals.
If you have one, grab your DMM and check the resistance across the Tubes terminals and that you have voltage at the amplifier terminals.
