The UTM3580 is a Push-Pull tube output transformer, 15kCT:600, 10:1, 5:1, or 2.5:1 ratio. Recommended for a vari mu output circuit like Altec 436. Open frame package.

Estimated Delivery:
48 Hours


For use in a high performance valve compressor/amplifier etc where high output level and exceptional bandwidth are required. Designed for use with Push-Pull output stage or an AC coupled cathode follower or SRPP circuit driving a nominal 600Ω line. Can be configured for low output impedance (10:1) or high level output (5:1) by connecting the twin secondary windings in parallel or series.
