Specifications:

・Fine Ceramic of Alumina 95% for socket base
・Thermal conductivity is exceptionally higher than the average ceramic socket base made of steatite.
・It restrains the increase of temperature and contributes to longer life.
・New method of direct gold plating
・Gold plating directly on the phosphor bronze without using nickel ground lowers magnetic distortion and achieves ideal quality for audio (for S-7Am, S-7Am-P-GP)
・RoHS compliant
