>>UPDATE<< In case you have your own tubes and wanted to buy this preamp even cheaper -> without 3x12ax7 tubes - I can remove them from the offer and reduce the price accordingly - let me know! Up for sale is a chinese factory assembled (not DIY kit) Marantz 7 line preamplifier clone.It has not more than 5 hours on it so all the components and tubes are like new and need some more burn in time. Even now before full burn in it is the best out-of-the-box preamp I have had for this kind of money, imagine what would happen if you upgraded some parts! Point-to-point wiring rules!Preamp has no hum/noise and trully black background of course it sounds way better with NOS tubes ( Ive checked it) Now you have a chance to save on time, shipping costs and customs duties because sale is within EU!
