While I'm in the progress of repairing my new to me Sansui AU-D11, I happen to be enjoying my old stereo. A KA-9150, Large Advent's, and Pioneer HPM-100's setup. Only when FM reception is better than 4 1/4 can I crank her to -30 on the old dB scale(Volume knob). I have an indoor dipole antenna oriented for best reception, connected to the 75 ohm, and about 150 feet of 14 AWG strung outside over my roof, connected to the 300 ohm. Seems to work best for me. How can I make it better?
