Yamamoto Sound Craft Siemens 7P tube socket

Compatible with Siemens standard 7-pin vacuum tubes

This product is a tube socket compatible with German Siemens standard 7-pin vacuum tubes. It is compatible with large vacuum tubes such as 211, 845, 242, 832, etc., and has sturdy mounting dimensions with a mounting hole diameter of 55mmφ and screw spacing of 48mm x 4. Designed to stably support heavy vacuum tubes, it can be securely fixed.

Consideration for reliable holding power and careful handling

Many older vacuum tubes have delicate bases, so special care must be taken when inserting them. This socket uses a pin fixing structure using round cutting to achieve a holding force without play. While firmly supporting the vacuum tube, it has a structure that prevents unnecessary stress from being applied, preventing sound quality deterioration due to vibration.

The socket body hasCompriteI cut it out and use it.Compriteis a material based on dried wood impregnated with phenolic resin, and has electrical properties comparable to Bakelite, but with higher strength and heat resistance. Therefore, largeoutput tubeIt maintains stable support even when in use, providing a firm tone and a reliable sense of stability.

Phosphor bronze pin and gold plating treatment

The socket pin uses phosphor bronze, which has excellent strength and spring properties. Maintains stable contact pressure over a long period of time and prevents contact failure. Furthermore, by applying thick gold plating on top of a base treatment that eliminates magnetism as much as possible, contact resistance is reduced and signal and current loss is suppressed. It is a specification that emphasizes reliability to bring out the performance of large vacuum tubes stably.
