The precisely machined structure does not wobble and securely holds the large and heavy GM-70. This prevents poor contact and sound quality deterioration due to slight vibrations during operation, supporting stable operation.\u003cbr\u003eFluoropolymers have extremely high electrical insulation properties and low dielectric constants, suppressing leakage and noise generation even under high voltage conditions. It also has excellent heat resistance and maintains reliable performance even after long periods of use.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/IMG_4840.jpg?v=1766138300\"\u003e\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch4\u003eStable contact with phosphor bronze pin and gold plating treatment\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cp\u003eThe socket pin uses phosphor bronze, which has excellent springiness and strength. It maintains stable contact pressure even when the vacuum tube is repeatedly inserted and removed, and maintains highly reliable electrical contact even after long-term use.\u003cbr\u003eFurthermore, by applying thick gold plating on the non-magnetic base material, oxidation is prevented and changes in contact resistance are suppressed. By eliminating the influence of magnetic materials as much as possible, we support highly transparent playback.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/IMG_4841.jpg?v=1766138300\"\u003e\u003c\/p\u003e\n\u003ch4\u003eKey parts for amplifier production with an emphasis on reliability\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cp\u003eYamamoto Sound CraftThe 4P tube socket for the GM-70 has been designed with particular attention to material selection and processing precision as a key part that reliably supports the stability and sound quality required for large triode amplifiers.\u003c\/p\u003e","brand":"ExAUDIO","offers":[{"title":"Default Title","offer_id":45658849607937,"sku":"gm70-4p","price":12630.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/IMG_4839.jpg?v=1766139961"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/collections\/14_EL_274_1024x1024_jpg.jpg?v=1710747588","url":"https:\/\/exclusive-audio.jp\/en\/collections\/vacuum-tube.oembed?page=5","provider":"ExAUDIO","version":"1.0","type":"link"}
