The Svetlana SK300A Air System Socket is designed for frequencies up to 30MHz. When the socket is used, connection is made to each of the tube electrodes except the anode, by means of concentric rings of spring-finger contacts. The SK300A requires significantly less blower horsepower and reduced pressure drop than the older SK300 socket. The Svetlana SK300A is an exact replacement part for the SK300A sockets manufactured in the West.
