I used a pair of Tamura A- 8711 transfomer as the ouput transformer in a 12B4a linestage preamp. The highs are very clear and detailed but there is absolutely no bass. Can anyone share your expereince or advice what I had done wrong? I cannot find the datasheet for the A-8711 on this forum on on the net. I got them used anyway. Perhaps they were not designed to be used with a DC current flowing through them as they were designed for input applications?

If all else fail, I will probably use them as my transformer IV in my PCM1794 DAC, but that is in the digital forum.
