I was fortunate enough to get this soft plastic (that is the housing, not the handset or caps) rose beige S-C from 1958. It had a frequency ringer and I had a SL ringer from another SC 1543 and put it in. It still doesn't ring. Can someone help?
I have enclosed pics of the before with the freq ringer, the SL (called a 74A) after installation, and the schematic (that was in the phone. The straight line ringer is currently hooked on position 5 on the network (red wire) and the black wire is on C1. (pics show this). What's the purpose of the black bumble bee tube- like things?
I love this phone! Feel free to move this to the technical section if you want.
1) Here is the original frequency ringer

2) Here is the straight line ringer installed (74A SL)

3) The schematic says to put the red wire on 15 and the black on c-2 but it won't ring this way either...

4) Currently wired left side of network with the red wire on position 5

5) Currently wired sl ringer black wire on right side position c-1

Try moving the ringer wire to c2 or jumper L2 to g. Make sure that other ringer wire is connected to 15 and 15 is jumpered to 3 or ringer wire is connected to 3. The black striped thin is a bad quality capacator to keep the ringer from causing the set to sieze the line unless off hook.I would replace it with a .47 microfared at at least 200 v size.

Thanks Robby. I have tried wiring it in all the positions that you recommended. It still isn't ringing. I do not know how to replace a capacitor or where to find a .47.
Perhaps someone has a SL straight line 1543 S-C that rings and could peak under the hood and let me know how it is wired.
Ok Dan, I opened up one that I have. It's from late 1964 and has the potted network. Here is how mine is wired, excluding switch wires. If you want me to run those down, let me know. I have one capacitor in front of my ringer. It's mounted to a terminal strip with a terminal on each end.

Red/Brown Striped wire is connected to the capacitor/terminal closest to the edge of the phone.

Thanks Dennis. The striker barely trembles now. (almost like a freq ringer) ,at least I know it can move. I will have to fool with it a little more.
Was yours the pretty bubblegum pink one ? I remember it a little bit
Dan,
You can get a capacitor at Radio Shack. You need at least a .47 mfd. capacitor at 200 volts as rdelius suggested. Hope this helps. Here is a pic of one that I have SC 1543 W Ringer black to L-1 and ringer red to capacitor . The other side of capacitor goes to C-2. Line in green to L1 and red to L2. L-2 and C-2 are connected in network. stub
Dennis- Looking forward to pics of your phone. stub
Dan, this one is a green one with the cut corners. It actually has a 426 tube inside. My camera battery died while I was getting the info for you. I'll post a photo later.
Stub, is this what you mean? And how do you connect it?

Dan,
Keep looking .47 mfd at 200 v stub
Dan,
I have used this one . 1 mfd. at 250v. I can find stuff in the store easier than their site!!!!! I'll keep looking to see if I can find the .47 Can't find one on their site.
Do you have any clip leads? Take the line in wires loose from phone, red and green and remove the long ,black ,ringer wire and the long , red capacitor (bumble bee) wire. Use clip leads to connect the ringer black to green, line in, wire and the capacitor red to the red, line in, wire . Don't touch any wire and call from cell and see if it will ring. Ring voltage is ac and it will bite, HARD!!!!!!!!! This will bypass the phone , in case you have issues in it. If it won't ring now you need to replace the capacitor and check again. stub
Thanks I'm off to R Shack tomorrow
Here's the photo of my capacitor and the 426 gas tube. I don't see a MF designation on this capacitor. This phone is marked 1546W.
After taking my Stromberg Carlson off the shelf to open it up to get the wiring for Dan, I plugged it in at my desk for a test drive. By the sticker I placed on it when I got it, I see I bought it in January of 2008, almost 3 years ago. It's been sitting on a shelf in my "dungeon" waiting for some TLC. After using it a bit today I thought I'd share a audio file of the ringer. For those that haven't heard one of these ring you may be surprised at how loud they ring. It reminds me of an old fashioned burglar alarm. I about jumped out of my chair this morning when it rang. The wav file is attached.
By the way, the eBay selling price was $24.30 not including shipping. I think the prices have come down a bit on them in the three years since then, or maybe not.
Dan,
Did you get it to ring? stub
Dennis,
Sweet green!!!!!!!!!!!!!!!!!! I have 2 off white 1543 W's . stub
Cool phones! The green one is quite nice Dennis. They have an interesting look about them, having never seen one live and only in pictures, they look like a cross between a 500 and something older, not sure what.
Ok stub. I got the capacitor. It is the 1mfd @250v.
I put the ringer black to L1 and paired it up with the L1 green . Then I took off the red wire from the coil that was attached to the bumble bee and used a clip to combine it to the capacitor on one side . Then I took the other wire off the capacitor and put it on c-2.
Your last statement was " L2 and c-2 are connected in the network." Does this mean I make a jumper wire from L2 to C-2? I am unsure about this. It still doesn't ring yet.
Thanks
Dan,
Let's bypass the telephone. Take your line in cord ,red and green wire, loose from phone network, the green is hooked to black on ringer. The red wire on ringer is connected to one side of the new capacitor , the other side of new capacitor will go to the red line in cord. If the ringer coil is not open , it should ring when called from cell.
If it won't ring after this, the ringer coil maybe open. We can check that next if you have a ohm meter. My ringer coil,disconnected ,ohms out at 5.89 k ohms.
stub
Dan,
What are the numbers on your network , below the Stromberg-Carlson logo ? Mine is - 210640 RA stub
Mine are the same numbers as yours stub, 210640 RA , dated 1-58
Dan,
Did it ring with the ringer isolated from network? stub
No it didn't. ???
Dan,
If this is what you ended up with and it didn't ring ,then the line cord is bad or ringer coil is open or new capacitor is open.
You could remove the cloth cover on the coil and see if you can see a broken wire where the black and the red wires are connected to the ringer windings. Anyway that's about all I can do from here. Don't throw away either one . They can be repaired!!! That's all that is left. stub
Fantastic pic, I am going to copy exactly what you did here and retry it tonight and report back.. Thanks for all your help, I REALLY appreciate it! 8)
Dan,
You are very welcome!!!! We will get it fixed one way or another....stub
Stub, I wired it your way, assuming the red and green go out to the plug into the wall. No movement on the clapper. Touching the clapper with my finger reveals very slight vibration. Do I take a little razor blade to the coil and remove the black cover and see if the copper wires of the coil are broken or fried or shorted?
Dan,
Hold off on the razor!!!!!! Try this first . See how much movement the clapper has with the spring removed. You should get about 5/16" movement using your finger. I have seen them with trash in them and not move. On your ringer ,the 3 screws on the bottom of ringer assy, can be loosened and move the coil away from the clapper pivot to increase the gap, with the spring still loose. You need about 1/16" or less of a gap. Then when we get the clapper moving , you can readjust the bells. Hope this helps. stub
Dan,
Sorry , I guess I'm blind!!!!!!! Go back to the above pic and bend in the bias spring retainer( tab ) like mine. I never noticed yours bent out so far. Bend yours in till the clapper rests gently against the left hand bell. Just tight enough to keep it from tapping when you dial from another phone. Sorry I never noticed it.
If it still doesn't ring give me a call or pm your number and I'll call you, at your convenience of course. stub
Stub, after bending the tab in, the spring has less tension and it rings. It wasn't an electrical issue at all, just "mechanical". I will clean the housing and post pictures, since I know wESTERN eLECTRIC rose beige 500's are popular and rose beige 1543 S-C's are seldom seen.
tHANKS!!!!! :D ;D :)
Here's the finished phone. It is a mix-the housing is soft tenite, the handset is ABS hard plastic, and the numbers plate is painted metal. The handset is a little larger than a WE500 and almost feels like an F-1 WE.

I have one of these in green also. They are great phones. Mine sits on my nightstand... and when it rings, it scares the heck out of me! If I ever slip into a coma, just call and it will snap me out of it. :D
