Sonic Frontiers SFL-1 Tube Hybrid Stereo Signal Pre-Amp

Here is a CLASSIC in really remarkable shape fresh from a checkup at the doc. Wherefromwhich a professional repair tech found issue only with the replaceable tube, added a fresh Tung-Sol 12AT7W and Voila! Sweet music into the Sonic Frontiers! The metal work is still close to factory fresh, it looks as clean on the outside as it does on the inside. The V/C is very smooth. My personal experience with this pre-amp is that it allows the influence of the amplifier behind it to really step forward with its own sonic signature. In other words, it makes your amp and speakers sound more like your amp and your speakers... hard to put this kind of stuff into words. In any case, thanks for looking. No box, but it will ship safe and sound, insured w. sig required.
