It depends on how big the connector shell opening is. We use RG174 for our black cable kits (about 1/8" diam.). This may be your best bet. There are somewhat bigger audio cable diameters that might work but it seems like the next size RG number is too big for most 1/8" plugs. -- Regards, --/////-- John Blacet Blacet Research http://www.blacet.com
