I was asked to repair four Kingston coils. Can someone identify these coils? I found three kind of coils in the parts catalogs of a few dealers.
I also should like to know what parts are available at this time.
Thanks

Hi André,

As I know RV Anderson is the guy about Kingston coils. He may help you finding answers as well.

Those are 1912 Kingston T-4238 coil units. All of their parts are available, as I rebuild them and also make complete correct reproductions.

Thanks R.V.
I will come back as soon as the coils arrive here.

The kingston coils arrived to be rebuild today.

As this is the first time I do these coils I have a few questions. (I did 24 Heinze coils in the past and they still work well.)

At there arrival, the first thing I did was measuring the resistance of the high tension (secondary) coil. By three of the coils I found 1.4 K-Ohm. The fourth was open. Is this right? or is this low and need the coils to be replaced?

Does the brown capacitor, sold by Lang, works well in these coils?

How do I get the brown filler off the coils? Heat don't work. Will it break down by hiting it with a hammer?

I will post some photos later today.

If the high tension winding is open it will need to be replaced. The T-4238 coil generally shows resistance in the 2500-2800 ohms range. The pine rosin originally used to pot these units can be carefully removed with an old screwdriver or chisel (don't use a hammer) enough to get the new thin style condenser (the one Lang's sells) in, but generally once the glass is removed there is room enough without digging in to the rosin. The unit with the open windings can have them removed just about any old way that saves the wood.
