Hammond Mfg. Co. Ltd., Electronics Division www.hammondmfg.com 125DSE UNIVERSAL SINGLE ENDED TUBE OUTPUT TRANSFORMER  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 (see graphs for detailed response).  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.
