Spare Arc-Plugs for Alpha Delta Switches

Many of us use Alpha Delta coax switches in our stations for antenna selection. These switches use Arc-Plug gas discharge tubes as lightening protection. Spare Arc-Plug elements sell for $10 – $12 from the traditional ham retailers. Mouser Electronics  sells them for $2.37 each in quantities of 10. P/N 576-CG21000.

Duke went to the site with a “corona detecting camera” presumably to detect any arcing on various power components. This corona is the electrical arcing kind, not the drinking kind nor that other one in the news lately. They found 12 leaking insulators! Duke has ordered the parts and will contact Dave again once they are replaced. That will hopefully significantly reduce the noise level at the club … Click for more
