{"type":"firestarter.listing","listing":{"id":"lst_iiIV4bKN","product_name":"Mullard M8162 (CV4024/ 12AT7WA) Vacuum Tube","category":"Vacuum Tube","description":"The Mullard M8162 is Mullard’s military-spec 12AT7, built to tighter tolerances than standard production tubes and screened specifically for low microphonics and long service life. It was originally made for communications and instrumentation work, where stability at high frequencies and predictable behavior under continuous operation were non-negotiable.\nArchive Assessed, Apos Assured\nAll Archive tubes are thoroughly tested, inspected, photographed, and inventoried, guaranteeing the quality of each tube that's shipped to customers. All tubes carry an Apos 12-month warranty against manufacturing defects. \nAre the tubes...dusty...?\nBecause these are genuine New Old Stock tubes, small cosmetic irregularities may be present. These aren't defects but artifacts of vintage manufacturing and decades of storage. They have no impact on reliability or sonic performance.\nSpecs\n\n\nBrand / Type: Mullard M8162 / 12AT7WA / ECC81 / ECC801 / ECC801S / E81CC, 12AT7 / 12AT7A / 12AT7WA / 12AT7WB / 12AT7WC / A2900 / M8162 / CV4024 / CV4034 / CV455 / 6201 / 5965 / 6060\n\nGetter Type: Ring Getter\n\nMade in: England\n\nTested on: Amplitrex AT1000 Advanced Digital Tube Tested\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427152.jpg?v=1771372631","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427153.jpg?v=1771372568","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427154.jpg?v=1771372508","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427156.jpg?v=1771372450","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427155.jpg?v=1771372388","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427151.jpg?v=1771372330","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427157.jpg?v=1771372268","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1218427158.jpg?v=1771372208","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-mullard-m8162-cv4024-12at7wa-vacuum-tube-1220503277.png?v=1771366748"],"price":220,"currency":"USD","in_stock":true,"inventory_qty":89991,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.985Z"},"share_url":"https://firestarter.network/l/lst_iiIV4bKN","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
