Type 1480 Source 3 Ohms load 3000 Ohms
FEATURES Multiple interleaved
windings ensuring exceptionally virtually flat response from 10 hz to 120 KHz. Negligible phase shift ensures a unique sound with excellent transient response. Balanced two chamber winding. The two chamber winding also
ensures the two secondary windings are identical in resistance,
capacitance and coupling factor resulting in almost perfect phase split
drive to balanced amplifier even at high frequencies. A relatively large core ensures negligible harmonic distortion. Can be configured for 1:10 or 1:5 ratio. Mumetal
can for magnetic shielding. Available with threades grommet or M3 threaded mounting holes. See HERE |

CONFIGURATION For normal 1:10 use to an unbalanced input connect Orange to Blue and insulate. For push-pull use Orange-Blue as the center tap. For 1:5 operation connect White to Blue and Orange to Grey |

APPLICATION combines the functions of a cartridge step-up transformer and a highly accurate phase splitter for use in
phono stage amplifiers using balanced transistor or valve circuits.
Ideal for push-pull power amplifiers. Can be driven from a cartridge with balanced or
unbalanced cable. Provides
high common mode noise isolation. Suitable for cartridges in the range 2 to 15 Ohms.
Replaces Sowter type 8055.
