SOWTER AUDIO TRANSFORMERS
1480 STUDIO CARTRIDGE SUT TRANSFORMER WITH OUTSTANDING BANDWIDTH

EXCEPTIONAL PERFORMANCE TRANSFORMER WITH FULL GEOMETRIC BALANCE.

Sowter 1480 SUT Frequency  response

Type 1480 Source 3 Ohms load 3000 Ohms

TRIAD HS-29 replacement
FEATURES Mumetal core for minimal harmonic distortion. 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.Mumetal can for magnetic shielding. A relatively large core ensures negligible harmonic distortion
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.
