Recently, Ric Schultz posted that he recommended the Jantzen Wax Coil inductors instead of the Erse for HF extension and air, among other things.
I have asked Jantzen the following question, only to be told they don't know and have absolutely no idea:
Is there any potential harm in cryo-treating (to -310F) the Jantzen Wax Coil?
I cannot see any possible harm, other than changing the sonic signature, possibly dramatically (which is a very valid concern, in my book.)
But maybe I am wrong, so I figured I'd ask two of our most beloved super tweaks if they have any experience in this regard, or if none, any theoretically-based concerns about what might, or could possibly happen.
Same goes for the other members of the Tweaks Asylum. If you have any experience cryo treating wax coils or similar, chime in and share, if you've a mind to.
Thanks to all, and as always, Happy Listening!

Sorry Winston, No experience with beeswax, although like you I suspect the typical slow drop times and rise times will not have any negative impact on the wax.
The website does state that the coil is hard as a rock and that some kind of polymerized paraffin is used. In addition it states that paper is used as insulation, making for penetration by the wax. My guess based on what I have read is that the coils are wound fairly tight and that the paraffin is there to insure there is no "flexing" of the coils from the fields generated. Inductance should be very constant that way.
Since the coils in the photo look quite solid to begin with and the amount of paraffin is barely visible , I doubt if there will be many issues, just make sure the temperature drop is controlled. The fact that the coil is 100% "encapsulated" means that it will take some time for the temperature to penetrate the coil's center.
Perhaps if the cryo facilities are reasonably close you could place in a frig and then in dry ice for a few day to insure the core is lowered in temperature.
The facility is in the USA, so no chance to do what you suggest, but good thinking, no doubt. If it was nearby, yes, then I definitely would consider a pre-conditioning slow-drop of temperature.
Again, many thanks for your kindness in responding.
Cheers!

Some of the wax might separate from the metal. I would be careful if you are putting it directly into liquid nitrogen versus putting into nitrogen vapor.
In addition to the above concerns, I would wonder about the effect on the wax itself; would the wax return to its pre-cooled shape and consistency, when it was warmed to room temp? It might instead crack and even shatter due to the cooling process. Before doing this with an expensive inductor, I would recommend experimenting with a piece of wax.
Your concerns are noted and appreciated.
Not sure I'm going to do it yet, but I do appreciate all the input, pro and con.
Thanks! :-)

I've always wondered about that with any finished product with multiple materials involved.
For ex- a power cord vs just the wire itself.
...due to two different materials and how they change shape with the cooling.
