LONGHIN - Great Tube Testers from Italy
Speakers : Zeiss Ikon
Zeiss Ikon 50 cm Loudspeaker AlNiCo version

Paper cone originally treated with Shellack. Note the interesting stucture of the cone. Also note the ZI-characteristic little "dustbag" just underneath the phenolic spider to protect the voice coil from dirt.
