Interstage Tube Drivers

Hammond Manufacturing Interstage Tube Drivers are available in two styles: the open-style 124 Series with minimum 5" long primary leads, and the closed-style 126 Series with minimum 8" long leads. The 126 Series is designed for driver use only in single-ended tube output amplifiers. The drivers replace coupling capacitor circuits for improved sound, while the bifilar wound windings provide exceptional coupling and bandwidth. The 126 Series features a gapped core to support the specified DC bias current, along with 20Hz to 20kHz minimum frequency response and 400VDC maximum working voltage. The modules are hipot tested at 1000VDC.
