Thousands of hours…
Longer than a growing portion of solid state audio goods…

Preamp tubes like this barely increase the signal compared to power amps. The heater itself, inside of the tube, does slowly wear out, so it will not last forever, but as the previous answer states, it will run for thousands of hours before burning out. This tube doesn't get very hot and it doesn't pass much current so it will last for decades. Interestingly, unlike transistors, tubes do not go bad in the box. Some of the materials in transistors actually get old, even without use, and stop working. So in some ways the tube in this has the potential to last longer than the solid state components. It should also be noted that the 12AU7 tube is inexpensive and readily available. Those tubes are used in guitar amplifiers so there is essentially no chance they'll ever stop being made.

I’m 99.99% certain that you can’t simply because of the tube. Just like diodes, transistors, and the like, with the tube being their precursor it only allows current to flow in one direction. By running it backwards you’ll be pushing against the flow of current, hence it won’t work. There’s plenty of devices on the market that do what you’re asking and have no powered components to get in the way of the signal. Using this as designed should sound pretty good, but this is not the device that you want. Look for something simple and preferably not even powered.

Would I connect a CD player to this and then connect this unit to the analog input on my receiver? Would this improve the sound? I wish drop would include more details.

Yes, that’s how you would connect it. As far as “improving” the sound, depends what you’d consider an improvement. Will probably give you a smoother, more organic sound (due to the tube) than your stock CD player.
