Electrodes and cell's.
Wear part's of all our plasma tweeters are the electrodes and sometimes also the cell's. Over the years the electrodes get worn (tip burned away) or cell's are broken.
The material of the cells is quarz glass. There is no other material for that because of the heat from the plasma. The plasma has a temperature of appr. 1200°Celsius (2190°F).
The same is valid for the electrode. We need material which withstand these temperatures. Therefore I use Kanthal® A1. Melting point 1400°C(2550°F).
I know that some uses stainless steal for the electrodes but they don't last very long.
If you need some electrodes or quartz cells write me a mail. I am able to reproduce any electrode.
DuKane IONOVAC, IONOPHONE, IONO FANE
All these tweeters are the same. Iono Fane and B&W P2 are licence copy's of DuKane's Ionovac.
update July 2025
in the last 12 months I had so much requests for DuKane IONOVAC replacement quartz cell and electrode that I decided to make a batch of 20 set ( 1cell and 1 electrode) The cell is made in Germany by one of the country’s leading custom glass and quartz manufacturing houses. The cells are also ground outside for exact dimensions and are made to tighter tolerances than the original cell to ensure proper fit and purity of that unique Ionovac sound. The electrodes are made from high temperature Kanthal® for long life and reliability.
DuKane Ionovac Replacement Cell Kits are available now from stock.

This is a picture of the 2025 Batch. The cylindrical outlet of the cell is improved with a perfect conus.
Magnat MP-01 and MP-02
I am also able to manufacture electrodes for these kind of speakers.
MP-01 electrodes are longer than MP-02 electrodes so it is important to know for which speaker the electrodes are.
ATR TW-1 Ion - Acapella
One of my readers need's electrode for an old ATR TW-1 Ion. His electrodes were worn out and cell's are broken. So I have made a set for him. He uses my cell's. They are slightly different but I think it will work.
