The
Audio Type Transformers
125SE series. "Classic" Universal
single ended tube Output audio transformers.
Key
Features:
-
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 our 1627-1642
series.
-
For
push-pull output use, see our 125
series - 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.
-
