In stock
  • Designed for general purpose or replacement use (not Hi-Fi), in single ended, tube output circuits.
  • Frequency response: 100 Hz. - 15 Khz (± 1db max. - ref. 1 Khz). (For full frequency response (20 Hz. to 20 Khz.) - see P-T1627SE).
  • For push-pull output use, see P-T125A - optimized for push-pull tube output circuits.
  • Open style with minimum 12" long primary & secondary leads 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.
