124-110  Tube Socket, 7 pin, Equal to SK600, MFR: E.F. Johnson (124-0110-001)

 No longer available for Export

For ultra high frequency tubes. Also suitable for use with CRT bues 1EP1, and 1EP11 with E.l.A. base no. E11-22. Base material has low dielectric constant which results in low pin-topin and shunt capacity. Continuous heat resistance to 500 'F. Mounting lugs provide low inductance grounding. Three point mounting stability. Eleven pin configuration.

• Raised pads for excellent base pin cooling
• For tubes such as 3CX400A7, 3CX800A7, RCA 8072, 8121, and 8122
