Lundahl LL1690 Audio transformer

LL1940 is a high turns ratio transformer designed for tube microphones. Conventionally, this type of transformer has a mu metal lamination core for minimum distortion and maximum transparency. For the LL1940 we have chosen a silicon iron C-core (with approx 10 times as high distortion compared to mu metal) to add more “transformer character” to the signal. The transformer has an internal Faraday shield for optimal output balance, but no housing.
