Best of luck on your repair, @Fernando Achiary. I recall reading a post on the NHT Group on Facebook, from Ken Kantor (original founder and designer of the initial line from NHT). His post was about ferro fluid. He seemed to indicate that it was very very rare that the ferro fluid would dry up on his drivers - but that it was possible. Sounds like you came across the one that did. Looking forward to your update.

Hi everyone, it's been a few days since my last post, but I have some news to share. I finally decided to do two things. You might remember that I suspected the tweeters' ferrofluid was the problem. One of those things was to disassemble the tweeters to verify that the ferrofluid was indeed completely dry. I cleaned them as the tutorials indicate. The voice coil and domes appeared to be in perfect condition. I bought the ferrofluid on eBay. It hasn't arrived yet. The second thing I did was remove the crossover and find that it had been completely rebuilt and modified with some audiophile-grade capacitors. It's very possible this work was done in Argentina. I'll show you photos of what I found. Overall, they sound fantastic, but the tweeters are a bit recessed and dull. If it's not the ferrofluid problem, then I should check the crossover.

Welcome to TCS - glad you found us!

I still hope to come up with a pair of 3.3, someday. but now they are 20+ years old..., so the next question will be how to rebuild/restore/repair if needed. 😉

Since we've seen a few of your 2-channel configurations..., I'm curious to ask, @Daddyjt Mark, what is driving your Atmos (I'm sure you posted it before - but I forget). What kind of carver amplification is driving your atmos setup? I know @loner_t used to swear by the Marantz 8805 (IIRC) as a preferred dolby atmos head unit. What do you use for your processor/preamp system? I'm limited to 7.1 at the moment - but planning a future move a few years from now - dolby atmos likely coming into play. Thanks for the post, and keeping us on this leading edge of audio reproduction and experience in this thread.

Welcome to the Carver Site!! Very nice group of Carver equipment. Looking forward to hearing about the repair on the CT units. Much talk on the site here about the CT-6 and its power button, either broken or missing and the possibility of 3D printing replacements if one had an original one to scan. I have kind of felt that maybe the power button on the CT-17 might be the same as the CT-6's. The CT-7 has a rocker type which looks to possibly be a better application for on/off duty if one possibly wanted to convert the CT-6/CT-17 to rocker style switch. I don't have anyone of the three CT's mentioned here so its easier said than done for a conversion. These are just thoughts but...... Again Welcome!!
