Hello all. I’m in need of an RF choke for my Zenith 9S262 chassis 5905..
The Zenith part number is 20-135.
Does anyone have a cross reference to Miller or other coil manufacturers. Someone has contacted me with a large number of NOS coils and May have a coil that substitutes. Any help would be appreciated.
Dave Bertinot.

I don't have it but it is model 9s262. 9 tube not 6 tube.

It doesn't say in the Zenith service manual what value 14 is , it's center tapped and for one of the short wave bands .You will most likely have to have one out of a parts radio or have someone measure the inductance for you .

A photo of it would be nice .

That's exactly what's wrong with my 9S204 chassis. Mine has an obvious loose wire. I didn't notice the loose wire until I saw this posting.

Update: I was able to find the loose ends and solder them. You might try doing the same.

If you have an inductance meter would you measure yours to it can be documented for dbertinot and will make note of it in my Zenith manual II for others in need of the values .

Sorry, I don't have an inductance meter.

The part looks more like a BCB mixer/osc coil, not a simple RF choke.

A simple Chinesium LC-100A would be adequate to measure the windings.

If you do get one of these, make sure you get a "real" MingHe branded one, not a clone. Check the forum archives.
