Door Chime Buzz

[Ancient Iron]

I bought my wife a Ring Pro Doorbell for Christmas and installed it as per the directions. It worked fine. After about a month my door chime (I am sure it's original to the house built in 1955.) started to buzz and the plunger was pulsing.

I went to the transformer (NuTone 16V 30VA Which is the spec for the Ring bell to operate on) in the basement and noticed it only has two wires to power it black /white no green ground wire and it's mounted to a junction box with a light socket. Prior to mounting the Ring Bell everything worked fine.
My question is should I buy a new transformer with a ground and see if that works, I'm Thinking that since the new Ring setup is Electronic that it might be sensitive to grounding????
I'm running out of ideas

I would need more info, maybe a few pictures. I never heard of Ring Pro doorbell, but looked it up.
The original 1955 doorbell was extremely simple, just the transformer, 16 vac output to pushbutton(s) which may or may not be lighted, going to the bell...an electromagnet that the plunger rings a bell.
There's lots of information on line about the Ring Pro doorbell. I would check that then with voltmeter see if you're getting 16vac out of transformer.
Simplest thing I think would be disconnect Ring Pro, then you can measure there, existing wires that went to button. If 16v, touch wires together and doorbell should ring. If rings ok, sounds like bad Ring Pro. If you have 16v, no ring, check doorbell.

The transformer may be grounded through the chassis. is the j box its mounted on metal or plastic?

Also, did you install the white device across the chime terminals?

J box is metal White device??? not sure what it is.

J box is metal White device??? not sure what it is.

so its possible the transformer is grounded through the box then.

I couldnt remember the name of the white device.

Its the white box that comes in the pro power kit. has 2 leads on it. its suppose to be installed on the terminals on the chime.

looks like this:

I finally figured out the problem, I eliminated the wires to the rear bell and straightened out the wiring for the front bell.
Then I still had a bit of a buzz so I used the Ring pro power box and it stopped the buzz, I wired it one lead to the transformer term. and the other to front term.Also I had to go into setup on the phone and change the setting for the chime to mechanical instead of electronic( I didn't know about this when I first set it up) And so far so good

Thank you Sevenhills1952,Wyliesdiesels for your help.
