Line Output Transformers

Jensen Output Transformers allow manufacturers to guarantee "trouble free" operation of their products when customers incorporate them into complex audio systems. Transformer coupled outputs work equally well driving "Balanced" or "Un-Balanced" inputs and do not suffer from the stability problems encountered when connecting "Active Balanced" integrated circuit line drivers to "Un-Balanced" inputs with long cables.

Line Output Transformer for Vacuum Tube drivers.
Not designed for single ended Plate circuit operation.
Has single Faraday shield and horizontal channel frame mounting.

Line Level General Purpose 1:1 Bifilar Output Transformers
Unless otherwise noted, all are multifilar construction with either 50% ("L" types) or 80% ("M" types) nickel cores. Because they have no Faraday shield, these types are not recommended as input transformers. Characterized below for 0 Ohm source and 600 Ohm load.
