Carver C-4000/4000t Upgrade and Restore
Nelion Audio commented on Nelion Audio's record in Carver Preamplifiers
Changed Price to 400 -
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! Restore Price: $400 Gundry Filter for Sonic Holography: $40 LED color change: $40 Remote control Volume: $150

@tim Are you having trouble logging in your account?

Did you get it working Tim?

I will very soon. I'm actually working on it this month!

Well, I can tell you B & O is not always easy to troubleshoot. Those speakers are active and they have a display for volume of I remember. Best way to troubleshoot them is to test each of its subsection components. But I think if you follow up on ensuring the connections are solid and inspecting other failure areas such as capacitors and speaker drivers, you'll be in the clear!

Hi Tom. I'm working on both of those modifications. I've wanted a color solution for LEDs for a long time, it just happens to be a little complex when trying to keep the price down as well as accessibility without making major changes to the outside of the unit.

Restoral of this little gem involves replacing all electrolytic capacitors, reconditioning of the output transistor thermal isolators, replacement of critical resistors and pre-drive transistors, service bulletins and full cleaning inside and out. Full restore price: $350

Hey @Sk1Bum!

I have rebuilt them and it's hit or miss. If the brass bushings are worn, then no amount of rebuilding helps.
