A Brief Overview of a NuTone LA70 Short Tube Bar Chime Base 

You are the MF'ing man!!! I have a short tube from the 60's. Between 3 of your videos I have serviced every part. Solenoids, Stator and its board track. You're very thorough and are an excellent teacher. I have a new found appreciation for these old doorbells and would want nothing else for my home. Mine says clean with lighter fluid. Thanks again I couldn't have done it without you.

I grew up with this doorbell. 😁❤️ The Beverly Hillbillies use the same one. 👍🏻

This sounds awsome these are my favourite door chime

So glad I found this video. I'm going to purchase a Nutone LA305 and I wanted to hear how it sounds before I buy it. The westminster sound is just what I want.

I really like the sounds produced by these old bells with sound tubes.These days, they would be prohibitively expensive.But I really don't understand why manufacturers don't release electronic versions of that doorbells, sounds recorded on a flash drive, with the same sound quality.

I have a similar model from 1978, except the hi note's solenoid doesn't fire. And the transformer needs replaced. Although I fixed the hi note's solenoid, I just need to test it to be sure if I fixed it.

I have been thoroughly confused about this Nutone chime kit’s classification of what category it falls under, until now. Since I’ve been interested in this model, I see the chime bars and hear them play or sound off, when they’re are struck. To me and because of how Ring classifies this model, this is a mechanical door chime, because it is not playing a tune from a digitally recorded microchip. However, the description of this video explains and classifies this model as an electronic door chime. To me, electronic means digital. To Ring, it means the same thing and I believe we are both wrong. If i am finally understanding this correctly, the sound of this chime is a true classic door chime with respect to how it sounds. The sound is coming from little hammers or strikers which hit each bar. But how the strikers are activated is done electronically from the solenoids, as opposed to a mechanical motor, which used to move the little hammers. If I am correct on this please let me know one way or the other. I know other consumers are confused and are calling this a mechanical doorbell, too. In reality, there are or were mechanical door chimes and today we have mechanical (possibly), electronic door chimes and digital or digitally recorded door chimes, which are recorded on a microchip. Ring, I believe has thoroughly confused the public with their terminology and Nutone didn’t really answer my question either. Thanks for the explanation, which i finally think I am clear on.

I've had this unit for about 12 years. All of a sudden there is a 4 or 5 minute delay from when the button is pushed and when the chimes sound. Any ideas ?

14:13 for full chime

Need help. My grandfathers old NUtone LA-70 won’t chime anymore. When I test it the way you did with the common and to the front/side/rear. I get no chime when I hit the front?

Northside, are you still around? I watched your video. I have a question about the standoffs or rubber grommet supports for the chime bar dumbbell shaped rubber grommets that isolate the chime bar allowing it to chime. I purchased a Nutone LA305WL. However, one of the chime bars became disengaged. I was able to reinstall the dumbell shapped grommets back into the chime bar rubber grommet standoffs. However, I noticed that the right outboard resonator tube has the lower chime bar rubber isolator grommet standoff mounted at the top of the resonator while the other two resonators have the lower chime bar rubber isolator grommet stand off mounted lower into the resonator. Is this the correct installation for the rubber grommet support or standoff? Or do I need to lower it into the resonator. It appears to be mounted ok but I suspect a quality control issue on the standoff installation. I can email you a picture if you need more info. I can send to the email you have posted. Please advise.

I moved into my house 5 months ago and have a similar Chime that was working just fine until a couple of weeks ago. My wired doorbell button lights up, but when it's pressed nothing happens. Any ideas?

Hi Chris, I have a Miami Carey 8 Note long tube door chime from the late 60's or early 70's I don't know if you can fix it. I tried and cleaned the selenids and they work fine, but the motor does not turns the whole circle. And sometimes the selenoids stays connected, need to push the button again so the circuit can open. I was wondering if you can help me

I have been looking for a chime like this? Is it possible to buy one now? Can you give me any leads?

Could you please make a video showing how to install this type of door chime to replace an existing door bell? and also: is this type of door chime compatible to the Ring doorbell? Thank you!

is this the same base as the Broan-NuTone C306

Hello Ron my name is Ron a well. I am replacing all of the solid state components on my chime just to avoid diagnosis however, I have not been able to identify one component. Do you know what type of Transistor is at Q1?

Inam looking to buy something like this for my new home. Any suggestions and where to get a true mechanical door bell?

How do I bench test one of these? What is the yellow wire attaching to?

Can the chime/tune be changed from the ones that comes with it?

I got one like that the only problem I got is I have to keep my finger to hear all the tones… any solution for that

Hi . I have rittenhouse 4 tubes. Can you fix it
