Universal Single-Ended Tube Output

 

Key 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).
• 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.
