Believed to be new or slightly used. May be a little tarnished. Only includes what is seen in pictures. Used in Ham Radio, Induction Heaters, Plasma Generators, and RF Generators. The EIMAC SK-740 Air-System Socket is recommended for use with the tubes listed or other tubes having this special breech-block base. This socket is not intended for use with an Air-Chimeny, but is particularly useful in applications where transverse air cooliing, heat-sink or immersion cooling is intended. When this socket is used, connection is made to each of the tubes electrodes except the anode. The SK-740 socket consists of five sets of ring contacts: they are from top to bottom: 1) screen-grid, 2) control-grid, 3) cathode, 4) heater, 5) heater. Each set of contacts consists of six seperate contacting tabs. The tube elements are connected to their external circuits by two diametrically-opposed solder tabs. The SK-740 has no grounded contacts. The mounting plate of the socket is fabricated of nickel-plated brass. The contact rings and tabs are of beryllium copper, heat-treated after forming, then silver-plated. The rivets and washers are of brass, silver and nickel-plated respectively. The ten contact terminals are solder-dipped to insure firm, dependable solder contact. The insulating wafers adn the stop yoke of the socket are molded of a flameproof diallyl meta0phthalate. The SK-740 Air-System Socket is designed for under-chassis mounting and requires a 1.593 inches diameter hole through the chassis deck. Four screw holes are provided for fastening. * 4CX300A/8167 (Seperate means of directing air is required) * 4CX300Y/8561 (Seperate means of directing air is required) (this posting is the responsibility of the poster) |
