I am currently putting together my old JVC sound system. I really want the record player going - a JL-A15. I have bought a new belt and needle and have 'unfrozen' the spindle. I tried to connect it to my current amplifier (Marantz) but at full volume there is only a little sound. I read somewhere that a phono player requires a pre-amp, so I pulled out the old JVC JA-s11 integrated amplifier and connected it to the phono but I still have the same problem - there is a very little sound coming from the speakers at full-volume. Any ideas?
