Hello all, I am setting up a desk nearfield system. I got some Mimimus 7s, and I picked up an SA-100B to drive them. The SA-100B is not working. It has two ins, an RIAA phono, and a regular one labelled "Tuner". I can get sound when I play through the RIAA in, but the Tuner in is silent, I just get a bit of static. Before playing anything, I cleaned all ins/outs and pots with deoxit. The switches are a bit harder to get to, so I didn't clean them. Given that I can get sound from the phone, and not the Tuner in, I'm assuming the issue is somewhere either in the preamp or the switch (certainly hoping for the switch). Anyone have a service manual or schematic for the SA-100B, there is none on either the AudioKarma Database, nor on Hi-Fi Engine. Any help would be appreciated. I'm finishing up graduate school over the next two weeks, so this may be a bit of a backburner type of thing until then, but I would love any input I can find. I did notice, that when I played the audio through the Phono in, that it was pretty quiet, I'm wondering if the pre isn't working, and I was just hearing the transformers amplify the signal.
