I put my hand on the sub and it barely vibrates... and the sound is definitely not there! When the switch is in the up position the sub seems to be working fine.
Please tell me what might be wrong and what I can do to fix this issue!
Nothing is wrong with your Tube. The switch you are referring to is the Input Phase Switch. When in the correct position, you will have bass output. Whe in the incorrect position you will have no bass output. You can read more about the Input Phase Switch on page 19 of your owner's manual.
