Universal Single Ended Tube Output 125SE Series

Audio

Features

  • Designed for general purpose or replacement use (not Hi-Fi), in single ended, tube output circuits.
  • Frequency response: 100 Hz. - 15 Khz at full rated power (+/- 1db max. - ref. 1 Khz).
  • For full frequency response (20 Hz. to 20 Khz.) - see our 1627-1642 Series.
  • For push-pull output use, see our 125 Series.
  • Open style with minimum 12" long primary & secondary leads.
  • All sizes use butt stacked cores (using 29M6 steel) with an air gap, to reduce D.C. core saturation.
  • Primary impedance range from 2,500 to 10,000 Ohms.
  • Secondary impedance range from 4 to 32 Ohms.
