hello from Atlanta area. Just found this forum and I'm anxious to get more info regarding my old Carver MRX-150. Still using it and was somewhat repaired a few years ago but not completely updated. Now the balance know is causing static when rotated since I very seldom used it since I bought it way back on the 80's. No big deal since I still never use it but I'm pretty sure is the pot. So, wanted to know if there are clear instructions on how to clean/lubricate it and if it's something that a novice can do. I've looked at several videos but none clearly shows how to get to the balance knob and where to spray the cleaner (Dioxit 5?) Also, I'd like an honest opinion on the difficulty on recapping and updating all the pieces that are suggested being replaced. About 5 years ago the speaker relays were replaced. Thanks

I have two TFM 75 in good to great condition, a friend would like to trade me a beat-up but working PT2400 with some cash coming my way, what does the community think is fair. Thanks.

First Welcome to the Carver site!! The last 75 I looked at went for $2000.00 The restoration of a 75 will cost $1200.00, and I can only assume it will be the same for the 2400. I don't know if this is a good representation of the trade, but this is how I visualize this swap. What you have, What will be traded to you plus some cash, In the end its whatever makes you happy.

Hello Reel Bond and welcome to thecarversite.com. Glad you found us. As Charlie pointed out, the TFM75 amps are rare and expensive. Personally, I'd say no thanks unless the cash boot was enough to replace the TFM 75. I did a search of the various auctions and audio listings, and there aren't any TFM 75s listed that I could find. The last few listings I've seen have been in $2K range, but I don't know if they sold or not. Occasionally you will see a listing for $1500. From what I've read here, the PT2400 is the professional version of the TFM 75. Both amps are discussed here is several threads, and maybe some of the folks with first hand experience will chime in. I hope that helps.

Just my 2 cents worth but unless this contact is going to hand you a large wad of cash as well as the PT2400, I would keep the TFM75s as they are very rare amps and almost impossible to find. I would send the amps to Greg at Nelion to be restored and you will never go back... Nelion Audio - Authorized Carver Repair

They never get old. I can cue up all 20 albums that I have on the WiiM, and Jazz Cat all day long.

I load the 390 with 5 Ripps then sit back and enjoy!!

If you ever question yourself about the first dose, its always best to be safe and just have a second dose. Just to be safe.

From Montreal Canada , still using my 500-t mkII that Riich modified still sounds great

That's a great visual on how this deal could go down. I would still stick with the TFM 75s if at all possible...YMMV

Excellent idea!

This is quite an early dose today. Im thinking you may need a booster late.

The advise I have already received from this site is both amazing and much appreciated! I will certainly look into this in more detail when time permits and would document and share the results with joy. In the meantime, it is my wish that each of you have a Merry Christmas and a healthy and happy New Year!! Let the music live on 👍

I also like your idea of a double dose.

Im glad that you are careful and never miss a dose!!! Can always listen to the Rips.

I agree totally with what Andrew has spoken; I have one of those "Never Again" experiences with a 'Kit (Mismatched, Missing or low grade and just generally poor parts)' from many years ago working on a TFM 35. 4krow knows EXACLY what he's doing (He refurbished 2 of my C1 (BillD) preamps and they are still going to this day; Good luck with the project and post some pics if you can!

The general consensus here on TCS is that "kits" are very risky..., they can include sub-standard, often no-name parts with dubious quality and tolerances, if they even state them at all, and sometimes wrong, or missing parts..., and you are stuck with them. Lots of eBay "never again" stories on kits for Carver refresh parts here on TCS... Also, by pulling the cover off your C-9, and building your own BOM ( @4krow gives you a head start ), you can achieve the following: Choose the quality of parts you want (Nichicon and Panasonic are preferred, other lesser-known brands may not have the same high level manufacturing tolerances you want when you put this time into refreshing your c-9..., last thing you want to do is introduce problems from substandard parts. Order exactly the parts that your C-9 needs. Experience shows that Carver Corp., had many revisions to the C-9 over the life of production. And also variations in the build on the assembly line..., if you want to put your C-9 back together the way it was originally built on that day it was manufactured, you want to put the exact parts back in - the only way to know what those were is to open it up, and write down the capacitor specs (physical: size (diameter, height, and electronic, uF rating, v rating, temp rating, etc.). Most of us use Mouser.com, or Digikey.com to purchase parts to refresh electronics. I personally like Mouser's menu-based interface to plug in all these parameters, and get back the options that they source and carry..., including the reputable brand names of Nichicon and Panasonic..., (there are other reputable brands - these are just the most common in my head as I type). It would be great if you would memorialize your project in a thread here in the Processor Forum section (this thread is in the "Welcome" section..., so starting your own project thread can get more member's eyeballs on it, to help you as you work through it.) Post your BOM, pictures of your c-9, pictures of your progress, pictures with questions you have as you work through it, and final pictures of your c-9, and your entire system cranking out tunes with your accomplishment added to your audio stack1 Looks like you have a fun project, and I need to get motivated on mine, to get it done. 😉

Not so much a specific kit, but maybe a BOM. 1) 2 ea.- Nichicon Muse bipolar 22uf, 25 volt capacitors 2) 3 ea.- 1uf, 25 volt Nichicon electrolytic capacitors 3) 4ea.- 1,000uf, 25 volt Nichicon FM electrolytic capacitors. Make sure that the caps are no taller than 35mm. 4) 1 ea.- possibly a red or blue led if you damage the original getting it out. 5) 1 ea.- 680pf MLC capacitor That is just off the top of my head. And if you want to replace the RCA jacks, I use Manley Labs for all of mine, but you have to clip the washers so that they don't interfere with the next jack or the circuit board. It is a tight fit, but well worth the effort. Oh yah, while your in there it is pretty easy to replace the AC plug with a snap in AC inlet. Then you can cap the hole for the original AC inlet. This allows you to use a detachable cord if you want to do that. After all of the units that I have rebuilt, it just seems automatic to do these as a basic upgrade of sorts.
