This is the second reference to color. I assume the color of the plastic. My 64 or 5 Zenith has what I consider to be the more common of cloverleafs that I have seen being that each magnet casing is the color of the electron gun it is controlling. So mine is red, blue and green. It's not a replacement and looks like the ones I saw decades ago. What am I getting wrong? Just curious....

My two broken ones are entirely off-white, not RGB.

Yours are the original Zenith issue.
IIRC, the last two model years, probably M & N, Zenith decided to use a purchased cloverleaf, instead of their own. They still made the convergence control board with the coils that would crumble. |

I changed a LOT of cloverleafs in the day.
21" sets employing a cloverleaf had (interchangeable) magnets used for static adjustment. They were not color coded. Period. They were identical and could be used with any convergence coil. I sometimes had to swap magnets when they became weak and not give the range on 1 gun but would on another. I believe the wires going to each of the 3 coil assemblies were color coded. 25" sets had the 3 separate color coded plastic encased coils with magnet that when assembled was the convergence assembly. I don't remember any 21" tubes using the encased assembly but I guess it is possible. Last edited by reeferman; 09-10-2015 at 05:35 PM. |

What color is your NOS cloverleaf, Reeferman? White, or RGB?

What is in your picture is not a cloverleaf in the traditional sense of the word..
If you went to a Zenith parts distributor and asked for a cloverleaf, you would not get one of those. If I can ever figure out Windows 10 I'll post a pic of one. |

That's the cloverleaf in the traditional serviceman's jargon.

Both are cloverleafs in my servicing world - convergence yokes, convergence coil assembly, convergence housing.....all clover leafs.
The question is can one be 3D printed - the white cloverleaf is what folks are looking for. You answered "Nope, same color" so some (including me were still unsure of the color - was it the RGB type or the white? - which is the purpose of my clarification posts. So I presume you have a NOS white cloverleaf?

Here's another reference picture of a white one that was posted by another VK member a while back. Sorry I don't recall who it was. Interestingly my Zenith 5119(chassis 25LC30), which I thought was a 1964 model, has the red/green/blue version. So it may have been replaced at some point.

Yes, I now remember the multi-color convergence assemblies on the newer roundies and the rectangular tubes. Thank you. I don't ever recall having to replace one.
I was in the service world during the period, and asking for a replacement cloverleaf at the parts house got you the "white" one. Remember, this thread started out looking for a replacement "white" cloverleaf for a '64 Zenith. Not the multi-color assemblies. |

Doug may have one in the RGB style, seen in his video for his 25MC30 set: https://www.youtube.com/watch?v=Mo8n3jLoM_U At 1:46 in Doug's video you see the RGB Convergence Assembly, what Zenith used in later years, when they abandoned the white cloverleaf and coils. Interchangeability is assured if the plugs on the assemblies are the same - the chassis are wired alike (per Telematic jig lit). I don't have one, but do have a line on a Zenith roundie combo of undetermined vintage - it's an estate sale regret a buddy purchased and stored in his uncles place. That's my only dog in this hunt. Cheers,
