DaVa FC-A1 a field coil contender

[LanschePlasmaGuy]

the DaVa can generate quite a lot of heat and it needs to be led away from the cart body
I was also on a general basis recommended the ebony by Richard, but it´s NOT suited for the DaVa
also the slots and headshell is too short for my Kiseki Blackheart or Koetsu Rosewood Signature Platinum

Thank you for the advice. I'll make sure to change the headshell for the metal version before I mount the Dava.

Maybe use an aluminum heatsink from model making. Simply take two longer screws and drill two holes in it and screw them to the metal headshell.

Correct idea, but insufficient solution to prevent your records from becoming crispy critters under the stellar radiation of a DAVA cart. There is a much more elegant solution from my PC building / overclocking days given the specific heat of water: 4180 J/(kg.K). My design also allows you to effortlessly run the FC wiring along the cooling apparatus. Please note : due to the heat generated by the DAVA which must be shunted away from everything not made of pure copper to prevent meltage/ignition, you will need a sizeable radiator.

Interestingly, the Lithuanian military has found a novel, non-sonic use for DAVA carts in cutting through heavy armour that requires obscene temperatures when thermite can’t get the job done. Large defense contract pending final approval, I hear. Typically military needs drive civilian applications, yet here you have the opposite where a significant engineering flaw turns out to be a driving innovation in the military-industrial complex. Go figure!
