IWISTAO 13W Tube Amplifier Output Transformer Single-ended Z11 0.35 Annealed Silicon Steel Sheet 0-4-8ohm for Tubes EL34 KT88 FU50 Audio HIFI (Model No: WVTR-OT13W)
The output transformer adopt core of Japan Z11 (0.35EI) Annealed Silicon Steel dedicated audio sheet, high quality oxygen-free copper wire coil package, and use pure pulp insulating paper between each insulated layer. Production process of output transformer defying cumbersome, adopt 2 out 3 clips or 4 out 5 clips method with hierarchical segmentation, placing paper with group by group, also with processes of meticulous, careful winding, vacuum impregnation, these lead to the transformer has good insulation and moisture resistant, transparent sound, sweet warm and mellow, excellent solution and clarity, as well as nice shape.
It is a better choice to tube amplifier audiophiles.
