Hammond 1640SEA

Single-Ended Hi-Fi Output Transformer

30 watts - 1,250 ohms - 200mA - 14H 


  • "Overdesigned" for high fidelity, single-ended, Class-A, tube output circuits (triode, tetrode or pentode tubes).
  • Enclosed (shielded), four slots, chassis Type "X" mounting.
  • Frequency response at least 20 Hz. to 20 kHz. at full rated power (+/- 1 dB max., ref. 1 kHz.)
  • Insulated flexible leads 8" min.
  • For maximum versatility, all units (except the 1642SE & 1638SEA) include a 40% screen tap for Ultra-Linear, tetrode/pentode operation (if desired). The 1642SE & 1638SEA do NOT include this screen tap as they were designed principally for high impedance triode tubes.
  • High-quality laminations, (M6) grain oriented silicon steel.
  • The core is gapped to reduce core saturation in Class-A tube amplifier circuits.
  • For general purpose or replacement use in single ended tube output circuits see our 125SE Series
