The Carver C-19 is a unique design, both in terms of its features and its circuitry. It's most notable feature is its vacuum tube output stage. In every respect, it is a solid state pre-amp, however, both the Main Output and Phono Amp stage utilize vacuum tube 'buffers' that create that coveted organic feel in the music signal. This preamp is considered a flagship of the Carver era, and there's many reasons to accept this status. Close attention to detail and the preservation of the fidelity of the source material is what this preamp is all about. The signal stages are meticulously designed to

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 c

This service is a full restoration and upgrade which includes cleaning inside and out, replacement of all consumable parts, reflow of questionable solder, service bulletins, new LEDs (your choice of color) for the meters, new 5-way binding posts, high-quality output relay, and the mkII upgraded components. This mod gives your 500(t) a much higher power rating, more headroom, less commutation distortion, better current sourcing and performance into low impedance loads, and tighter bass and transient control. We are the only techs authorized to perform this mod. Any other 'pros' out there c
