What Antek does

AnTek Products Corp (DBA Antek) is a US-based private company that designs, manufactures, and sells toroidal transformers, linear and bipolar power supplies, and tube-amplifier components through a direct-to-consumer e-commerce storefront. Founded in 2004 and operating with 1-10 employees from a Syracuse/New Jersey base, the company's product portfolio spans three transformer lines — AN series (10VA-400VA general purpose), AS series (50VA-400VA audio with static shielding), and AU series (25VA-4KVA industrial, UL-certified for 208V/240V/277V applications) — complemented by toroidal output transformers (MS/MP), filter chokes (LK), tube-amp chassis, covers, mounting hardware, and modules. The AU industrial line holds UL E497714 and IEC EN61558 certifications with dielectric testing rated to 3500Vac.

The core technology is toroidal transformer design achieving 95-97% efficiency (versus standard EI transformers), with heavier-than-standard copper windings, static shielding between primary and secondary coils to reduce magnetic leakage, low mechanical hum, and lower heat generation. Antek's primary customer segment is DIY tube-amplifier hobbyists and audiophile builders constructing high-end vacuum-tube amplifiers, with a secondary segment of industrial/electronics manufacturers needing UL-listed transformers. The company positions itself as a one-stop tube-amp component supplier with cross-compatible transformers, chassis, covers, and accessories.

The business model is exclusively direct-to-consumer e-commerce via a BigCommerce-powered storefront with no third-party resellers or physical retail. Revenue comes entirely from one-time hardware unit sales priced from $3 (mounting brackets) to $435 (4KVA industrial transformers), with tiered bulk discounts of 5-15% for orders of 6-49+ units. Marketing is limited to organic channels: an SEO-optimized website, Twitter (@AntekInc), and an email newsletter signup. The company is independently owned with no disclosed institutional backers beyond a single $200,000 NYSERDA grant in December 2011, and no management team, M&A, or partnership activity is documented.

Core offering

AnTek Products Corp designs, manufactures, and sells toroidal transformers (AN, AS, AU series), linear and bipolar power supplies, tube-amplifier output transformers and chassis, filter chokes, and supporting accessories (covers, mounting brackets, soft-start, fuse, rectifier, regulator modules) directly to customers via its own BigCommerce e-commerce site. Products serve both audio (DIY audiophile tube amp builders) and industrial (277V equipment manufacturers) applications, with UL-certified industrial lines and static-shielded audio lines for low magnetic interference.

Product overview

AnTek Products Corp is an e-commerce company specializing in toroidal transformer technology for industrial and audio applications. The product portfolio centers on toroidal transformers across three main series: AN series (10VA-400VA general purpose with noise shielding), AS series (50VA-400VA audio transformers with static and magnetic shields), and AU series (25VA-4KVA industrial transformers for 208V/240V/277V applications). These core transformer products are complemented by linear and bipolar power supplies (50W-1000W+), single-ended and push-pull output transformers for tube amplifiers (MS and MP series), toroidal filter chokes (LK series), and tube amplifier chassis. A comprehensive range of mechanical accessories supports installation, including CA steel covers, CH hold-down assemblies, CL vertical mounting brackets, SS soft-start modules, FM fuse modules, rectifier modules, and regulator modules. All major transformer lines feature UL certification (UL E497714) and IEC EN61558 compliance, with dielectric testing up to 3500Vac between primary and secondary coils.
