    The Carver C-4000 and 4000t are similar but also very different. However, restoring them and upgrading them are similar enough to include together. These preamps require a complete overhaul after nearly 40 years of use. We replace all the electrolytic capacitors with either high temp, long life type, bi-polar or low ESR where appropriate. We tear the unit down completely and recondition all the wipers on the attenuation knobs and buttons. Some units require factory updates and power supply fixes. All of these units also require the phono amps, time delay, auto correlator and sonic holography circuits to be tuned and calibrated. The unit is also cleaned and polished, fully tested and we listen to it to ensure it sounds better than ever. The results of our work are stunning!

     

    High quality parts and expert workmanship.
