Doorbell Wiring!

Is anyone familiar with the transformer-type doorbells? I have one in my garage and removed the transformer during a remodel because it was mounted on top of a junction box which was piggy-backed onto the junction box in the drywall - yes, it looked terrible, all sticking out of the wall. Are there any transformers I can get which don't have to sit directly on a junction box and can just be plugged into the receptacle? I guess I could just buy a wireless doorbell, but I'd like to keep the existing wired one if possible. Thanks!

BTW, this is the type of transformer I'm referring to:

You'll need to check the labels on your existing transformer or measure the existing one. Different systems can use different voltages.

Stamped on the Nutone transformer I removed was: 5VA 10V.

It's this one here: http://www.plccenter.com/Buy/NUTONE/515NA?source=GoogleShopping

is it still OK to use the 16v plug-in transformer shown above? Thankyou!


You may want this one instead:

I don't know if you pack-rat anything but older cordless phones and other odd house devices sometimes use 9 vac transformers. You may be able to use one of them.
Being 1 volt off shouldn't make much of a difference as most of those transformers generally put out slightly more than they are rated for depending on the incoming line voltage. It also helps that a door bell isn't a continuous duty device. If it was then the voltage would be more of an issue.
