Hi, I am in the project to assembly an active preamplifier, tube or transistor. I did some research, and I have a lot of choices.
My question is somebody has a preamp tube (6922 or ECC88) circuit with the possibility to avoid the input cap? I think (I am a newby!) that a preamp with a interstage transformer could do the job? Or, can I modify any preamp with the addition of a interstage transformer, and how ? Thank You
