Doorbell question
I have an older transformer driven chime system. The old transformer is a Rittenhouse model 180 115 vac input and 5va output.I believe it has a 10vac rating.I was at home depot looking for a replacement and several were available, but nothing at this size. They had one which is an exact replacement Zenith model 107-A but at HD its discontinued.
Any idea what I can replace this with if I can't find an exact match?
Thank you

If you have one chime and it is electromechanical any chime transformer should work.
10v would be for a doorbell not a chime. Chimes are usually 16-18v. Perhaps there was originally a doorbell and someone switched to a chime without upgrading the transformer.
I believe it has a 10vac rating.

The Heath DW-122 would be an ok replacement for your application. Just slightly larger. 10-16v at 10va.

Well you guys got me......I thought they were both the same, I'm sorry but its a ding dong type with the two tubes about 30 inches and a coil with a two way plunger.
Now is that a door bell or a chime?
The original transformer was 5va and 10vac.....

10-16v at 10va from HD work without frying it?

It may be slightly louder when it strikes but it will not burn up using that transformer.
It's only activated for a few seconds at a time.

Fun fact: Now days those two tubes you see are usually fake. The chime is usually just a bar in the case. In fact it is the same as a chime without the tubes. If you have an old one the tubes will actually make the sound.
