Looking for a service manual / schematic for a Cobra 29 NW LTD Classic. Build date March 2018. Board (29LNW) KEPC-1106-L3. Has the TDA2003. The Link http://downloads.cobra.com/CB/Models/29-SERIES/ does not work. Does anyone know where to go to find this now? Reading the post here, I see there are several different KEPC-1106-L boards. I would like to find somewhere to download all of them for my files.
