26F73

Low-power instrument and tube filament power transformer conforming to standard EIA RS-174guidelines, features a 117-volt AC primary input rating at 60 Hz, delivers a precise 6.3-volt center-tapped (6.3V CT) secondary output at a continuous 0.3-ampere (300 mA) current load threshold, 1500-volt dielectric insulation test rating, ultra-compact open frame channel-mount footprint designed for restricted-space electronics layouts, engineered to supply localized, low-ripple heater current to miniature vacuum tubes or pilot lamp indicator banks. Unit Sourcing Compatibility: This component came out of vintage signal generators, tube-based grid-dip meters, and compact tabletop radio receiver assemblies. Exact Industry Equals: Thordarson 26F73 and Stancor P-8385
