I have the above receiver and am about to re=cap it. On the top of the chassis, there is a long aluminum shield that is held tight with a wing nut. on this shield there is a label and mine is deteriorated beyond readability. Does anyone know what it says or have a pic of it?? I think that i have a replacement but not sure which one use. Thanks in advance for your time and help. Ralph Howes W8BVH
