Hi chuck: I agree completely - being able to find the information about the equipment I work on - is one of the original reasons I started making Videos - Chris

Hi eduardo: Without much more detailed information about the Syetem - its problems - what was done exactly - I can't really answer your questions - Of course it's always possible that it's the Speaker that's bad, however it could also be soooooo many other things - It would be best if you contact us directly about this System - Chris nscompany@msn.com

Hi Anne: You will need to conatct us directly about the parts for this type of Chime - Chris nscompany@msn.com

Hi N5PJ: Yes, tube amplifiers do tend to sound "warm" due to the distortion that tubes ininheritenly create - Chris

Hi jkerry: Well done and you're welcome. Glad that the Video helped - Chris

Hi locus-801: IM3003 are usually a fairly striaght forward modle to rebuild. It's not uncommon for some people to think that the Intercom System is outdate - It's common to have the use of the Intercom feature for communication to slowly become less and less over time ( as households grow up) - the Door Chiem is always an important feature for owners and while listening to the Radio is limited now-a-days, adding an external audio jack and connecting anothe rmusic source (I like echo dots) breathes new life into any system - Chris

yeah but he has blink door bell and the intercom makes the hum sound and when you talk into it it’s barely audible though you can hear the very disorienting voice ok but radio is bad and the fm signal moves back and forth I’m guessing something to do with capacitors? But I opened it up and the doorbell apparently my grandma says that 20 years ago they were sleeping and they heard the doorbell chime distorted over and over again play itself and no one was at the door opened it up back in December of 2023 and saw that the chime module had a burnt out resistor that was burnt off of it it’s black and crispy like toast lol

Not everybody knows what you do. I love that!!LOL

Hi joey: It would be best to contact us directly about the problem with your M&S MC602 - Chris nscompany@msn.com

Hi chris: Yes, you can conatct us directly about the External Audio Jack assembly - Chris nscompany@msn.com

Hi mysonicisthis: These are considered "Built-in Systems" All of the wiring would be concealed in the walls, usually installed during construction. Also, you need to consider that these Systems are from the ealry 90's and there weren't many choices for "portable" audio sources. M&S did offere in-wall cassette players and CD Players. I don't think that many owners would have thought to connect an external Audio Source through an input jack in thoses days - Chris

Hi loneranger: You will need to contact us directly about this - Please Do Not disassemble the IM3303 before talking with us - Chris nscompany@msn.com

Hi MIW_Renegade: I did the same project about 12 years ago when replacement LED lamp assemblies became available to fit outdoor incandescent landscape lighting fixtures - It was a good project and actually breathed new life into some of my overworked Trasnformers - Chris

Hi ronk: The Black & Gold M&S Models from the 1980's were by far the most popular home Radio Intercoms because of the looks - But, it was the 80's - Everyone wanted lots of buttons and if you added the matching CTG Cassette Player (the worlds mosty expensive cassette player, about $498.00 in 1985) you would have trippled the number of gold buttons and it even had Red & Green LED Vu meters, fantastic - If you stepped up to the N440, you would even more buttons! - But, it was the 80's. . . A time of excess and finding ways to show it off - Perhaps you would would buy a new Lexus LS400 in Baroque Red Metallic ($35,000 in 1989) and then drop another $400.00 for a set of 24K Gold badges. . . But it was the 80's - You have to have been there . . . - Chris

I don’t think it looks all that bad, as well as even though these units are obsolete to most people, I like the idea of having these units in houses still, I will continue to maintain and fix my unit

@@MIW_Renegade Not really as obsolete as people think. Since they're "built-in", removing them is usually more expensive (and a bigger hassle) than having it repaired. That's why we are always soooooooo busy - Chris

@@northsideservicecompany3567 we don’t use the intercom part of our system anymore, but we do still use the radio a lot, it’s just a nice feature to have, it definitely is very expensive to remove them, and in the next couple of months, I’m gonna be adding Bluetooth to ours so it’s more useable for us!

@@MIW_Renegade It's not uncommon for the Intercom use to become less and less over time, using the Music is always popular. Adding Bluetooth or even just an External Audio Jack to any System make it much more usable in today's world - Excellant idea - Chris

Hi iHeartindieGames: You can contact us directly about the Relay Boards - Chris nscompany@msn.com

Hi meyalliaguirre: I am unclear on excatly what you mean - However this Video may help: th-cam.com/video/vOm9FLeOzLI/w-d-xo.html - Chris

HI bigchevs: yes and they probably had to small of a screwdriver as well - Chris

Hi ronk: I have personally taken out many old Rittenhouse Intercom Systems when they were upgraded to modern NuTone Systems. I was never worried about reusing the existing Rittenhouse wiring, because it was such high quality. I remember the first time I replaced a Rittenhouse System which had a Sub-Master and the built-in Doorbell in the Master Station. - Chris

@@northsideservicecompany3567 I don't remember the doorbell at all. Either it never existed, or maybe the installers grabbed it for the repair of another unit. The wires on mine were all cut and surely used for the new installation, an IMA406 which I wonder if it's still there.

Hi groovy: I would say that a lot of thought and design went into their products. It seem sthat they were trying to create products that were miles ahead of what else was offered. This makes how Rittenhouse ended up even more tragic, always struggling and miles behind everyone else - Chris

Hi Michael: Very true and a good tip - Chris

Hi Bluecalcite1: We do not have springs for your Chime - If you search online for "nutone chime base" you will find that exact item for sale. It will use the same plungers and springs as your parents chime (check the picture carefully) - If you look carefully, you shuld be able to find what you need for under $20.00 - Chris

Thank you. Do you mean to search for Nu-tone bases generically and then sift through the results for an LA43, or did several models use the same base and I just need to locate a base that looks the same as the LA43?

Hi gdi9320: While I didn't ask Katie where she had the cover made, I suspect that since she lives in the San Francisco Bay Area, the cover might have been made at TAP Plastics. The not only sell plastic materials, they can do custom plastic fabrication. I have had times when they made custom items for certain installation that we have done - Chris

@northsideservicecompany3567 incredible. I'm going to find if anybody does that in Detroit since I live across the border. Or the Toronto area

Hi andrew: Be extra carefull with the 2-wires that are connected to the Motor Coil - Don't pull on them or stress them in anyway, otherwise the paper wraping around the coil will tear and the wires will come loose - Chris

Hi nicholas: No. "K" Model Chimes are difficult to find, especially complete Chimes with Covers and Tubes. If you do find one for sale, factor in that it will need to be completley refurbished if it's going to be put back into use. Also, be aware the the Tubes will likely be cracked on their tops - If the cracks are small (1" or less) it's not much of a problem, however I've seen cracks that are 2" ~ 3" long, which makes the tone sound flat and mostly usesless - Chris

@@northsideservicecompany3567 Thanks Chris. I actually have a complete set of tubes with no cracks just very tarnished and one of the tubes had lost the string loop at the top to hang it so someone had drilled a hole to MacGyver a hanging mechanism. I am going to try to polish the brass and need to follow your instructions on repairing the the striker, but the one side with a striker is functional. Any guidance would be appreciated. Thanks for your videos. I am trying to save this doorbell instead of replacing it given it is so cool and reminds me of the chime in my grandmothers house

@@nicholasmanolelis3968 Here's a link to our Video about making new Hanger Cords for your Tubes - th-cam.com/video/aV8rr0SXeZY/w-d-xo.html I am unclear about your questions regarding the "striker" - Chris

Hi DrDyDX: If you completely repurpose the existing wiring to power just the Nest Camera, it would fine - This means disconnecting the wires that you plane to use for the Camera Completely from the Intercom System (from the Door Station and from the Master Station) The other consideration will be, the power for the Camera. The Camera should have it's own dedicated transformer, although it it tempting to piggy-back the Camera on the Intercom Transformer - doing this on some models on Intercoms is mostly ok - some model not so much - Chris

@@northsideservicecompany3567 thanks for the reply! Since my current nutone system is pretty shot (none of the microphones work and all the speakers crackle badly) I just isolated the power supply from one of the two transformers and spliced power into the button wires. The design of the central unit was frustrating because the pin connector to the motherboard was GLUED ON 😡 ... But after cutting it off, and splicing it to the power feed, the nest doorbell worked perfectly! Thanks for your explanations!!

@@DrDyDx It sounds like to have a IM3303 System which needs a little attention to have it work well agian (considering it could be as much as 30 yeras old) A little cleaning and adjusting would get rid of the "problems' you describe - and BTW the Power Cables are not glue to the baord, they are soldered and they should hve been disconnted at the Transformers - not ripped off the boards - Chris

@northsideservicecompany3567 I've never seen green soldering, plus it was a plastic pin connector that connected to the board. I'm no expert so I'll gladly send you pictures if you'd like 😊

Hi PseudoSane: Mechanical 2-Note Door Chmes Chimes haven't changed much over the past 80+ years - The details may be different, but the basic designs are all fairly simular. If your 2000's Chime has electromagnetic coils - Plungers with Springs that strike Tone-Bars, it is very likely it is compatible - Chris

Hi groovy: Yes, It's truely an awesome Chime with a sound that's terriffic - Katie did a wonderful job with her 'showcase' installation - Chris

Hi rabiakhan: Perfect - Good to know it helped you - Chris

Hi kenneth: Glad the Video helped you with your Chime - Chris

Hi dragonman: Yes and thank you - Chris

Hi dhall515: The problem is the ever present background buzz - This is entirely an "age-related" problem - The IM4006 is not officially "old & tired" - Chris

Hi donna: Since your IMB313 is around 48 years old - There could be many, many reasons why there's no audio sound. Does the Radio play correctly? - Chris

HI bigchevs1: The 2 most common problems with the DMC and NM Series are 1) The Display Backlight LEDs fair and 2) The loss of any Radio Volume - Things to keep a watch out for - Chris

Hi groovy: You're welcome. . . More Videos to come - Chris

Hi msspear: I'm never really clear on how to respond to a comment like yours - You found the information you were looking for - but you're unhappy about how it was presented - I guess its like the old saying "no good deed goes unpunished" I will continue to present information on whichever topic I choose, in the format that I feel is best - Your "cankiness" will not deter me from sharing what I know - Chris

Hi UGotHooka: Your comment does not contian any useful, detailed information about anything I don't know what System your house originally had I don't know what System you bought I don't know why the original System was taken out You will need to conatct us directly and you will probably need to email use pictures of whatever id left of the original System and of the equipoment that you bought - Without details, I will not be able to help you -Chris nscompany@msn.com

Hi bigchevs1: I have been on a self-imposed Video Hiatus - After making 612 Video over the past 9 years, I needed a break. Thinga are actually going very well and we are in the midst of the Fall Repair rush. I have some interesting Video in-mind for the Winter Season - Thanks for asking BTW - Chris

Hi Extremely: The name of thie Chime is the "Symphonic" The chime it plays is a Westminster Chime (like Big-Ben) - Chris

Hi ron: I have no first-hand experience with the Wyze Camera - The problem you may encounter is - the wires that are connected to the existing Pushbutton ar enot 'power wires' and they may not provide enough power to operate the Camera - Also, depending on which style of Chime you have (fully machanical or electroniclly controlled) the Camera may not keep the Chime 'turned-on' long enough to complete its cycle - Chris

@@northsideservicecompany3567 I appreciate your response. Just to give you an update. I connected my new Wyze Video Doorbell v2 to my Nutone 8-Note door chime. Using their "door chime controller" which was included with the Wyze product and your directions for the wiring connections, I made the connections to the "front" door screw on the chime. I also connected my existing door bell button to the "rear" door screw on the chime. I also upgraded to a 16 volt x 30VA transformer.They both work with this setup. On occasion the chime misses the second of the 8 notes when the video door bell button is pressed. Thanks again for your video.

Hi shootingstar: What I explain in this this Video is exactly true and correct, I suggest that you review the information in this Video - What you suggest about adding a Transformer and Relay, is exactly what I show in our Video from 4 years ago - Here's a link th-cam.com/video/t6YswmDNVyI/w-d-xo.html Chris

Hi wrkey: I'm glad that the Video helped you - Chris

Hi hildazofrea: Thanks - Chris
