Audio Transformers for tube amp

Single Output Transformers

Wide band output transformers with third winding for NFB exclusive use, which can make stabilized NFB circuit, eliminating unstable oscillation through the changes of secondary load. Impedance for NFB winding is 16Ω. SG taps are provided for the models excepting F781, 782, 783, so that UL circuits can be constructed.
