1627-1642 Series - Tube Output (25 - 75 Watts) Single Ended - Hi-Fi

Product Features:
  • "Over designed" for high fidelity, single ended, Class-A, tube output circuits (triode, tetrode, or pentode tubes).
  • Enclosed (shielded), four slot, 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 and 1638SEA) include a 40% screen tap for ultra-linear, tetrode/pentode operation (if desired). The 1642SE and 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.
  • Core is gapped to reduce core saturation in Class-A tube amplifier circuits.
