{"type":"firestarter.listing","listing":{"id":"lst_6Wd_WsKE","product_name":"Philips EL84 Vacuum Tube","category":"Vacuum Tube","description":"Philips EL84 tubes are a cornerstone of classic European tube design: compact, efficient power pentodes that helped define the sound of countless hi-fi and guitar amplifiers from the 1950s onward. Produced across Philips’ network of European factories, these boast consistency, long service life, and a tonal balance that pairs lively dynamics with a smooth, harmonically rich midrange. \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: Philips EL84 / 6BQ5 / 7189 / CV2975\n\nPlate Type: Black Plate\n\nGetter Type: Ring Getter\n\nDome: Chrome Dome, Clear Glass\n\nMade in: Holland\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-philips-el84-ecc82-vacuum-tube-1218427135.jpg?v=1771369511","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427136.jpg?v=1771369867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427137.jpg?v=1771369929","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427140.jpg?v=1771372868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427138.jpg?v=1771369989","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427139.jpg?v=1771372809","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427141.jpg?v=1771372748","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1218427142.jpg?v=1771372687","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-archive-tubes-vacuum-tube-philips-el84-ecc82-vacuum-tube-1220503275.png?v=1771366869"],"price":230,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.990Z"},"share_url":"https://firestarter.network/l/lst_6Wd_WsKE","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
