Dead Kellogg 110a ringer fix
« on: March 03, 2017, 10:11:50 AM »
Hi everyone,

I sent a request to Phoneco for a replacement ringer and they kindly replied that I should try something first to make it ring.

"You need to jump the top 2 terminals on the magnet and it may work.  Ask for Mary the owner."

Mary offered to talk me through it but I don't trust my knowledge base to that degree.  Could someone please post an image of what this would look like?  When I get home I'll post pictures of the ringer in question.

Thank you so much!

This is a low-impedance unbiased ringer for a magneto phone ?

Unbeldi,
Uhhhh.  It is a model 110a that came with a Kellogg Masterphone model 900 (pyramid).  I don't know about the impedance or whether it is unbiased but it is NOT on a magneto phone.

Ronco is having you short out one coil at a time.If one is open,it might ring (poorly).

Several of the 900-series phones were indeed for magneto service. 900A, 950LR, and several of the 930s too.
What is marked on the bottom ?

110A ringers are non-biased type for use in 930- and 950-type Masterphones. (Used with hand generators.)

On the bottom is stamped 900SA.

These sets came in many configurations.
I don't have a reference for a 900-SA, right now, but only for a 952-SA in the 1941 catalog.  The 952-SA was a 952-LR with a 110-A 1000 ohm ringer.  So we should probably infer that a 900-SA was a 900-LR with a 110-A ringer too, which matches what you found.  A 900-LR was a 900-type delivered without any ringer, but it had a 109A induction coil.

So, it doesn't ring ?
Well, since it is supposed to be an instrument for magneto service, it probably doesn't have a ringing condenser.
Does it ring when you connect a generator and crank it up ?

I forgot that I had dug into this issue before.  This phone has a receiver element that looked like those found in candlestick phones.  As I recall, I thought that my phone was probably a combination of parts that had been recycled from older models that had been upgraded for someone who wanted a desk phone.
Here are the pictures promised.
Thank you for input!

Looks like a CB set, try to connect the 2 wires from the ringer to the terminals C1 and L1

So you have an anti-sidetone 106A induction coil, and a two-capacitance condenser pack with four leads.   One pair is for the ringer, and the other for the network.

The components don't seem like they should be in a 900SA, but they are Kellogg and are enough to make a working phone.
Have you traced wiring to see whether it can actually work?

Thank you for the suggestions!

I have traced wiring and tested conductivity and it seems to be correct and complete.  I swapped ringers with another K900. The working ringer still worked and the dead ringer was still dead.  That is why I was shopping for a replacement ringer.  I held off because I wanted to make sure I didn't need anything else and I like to try to restore the phone "correctly." If this was a magneto phone then I would consider trying to find correct parts to go with it.

From your suggestions, it sounds like I should go ahead and make it a CB set and replace the ringer.  Input?

Thank you,
Tina

Sounds like you got a broken coil on the ringer, or a poor solder joint for the wires.  Do you have a soldering iron ?   Melting the solder and letting it cool might resolve problems.

If you are looking for a new ringer, I would not buy the 110A, but a straight-line biased ringer, since the phone is already converted to CB set.
The catalogs tell you the numbers.

I will try soldering and if that doesn't work, I'll look for a different ringer.
