Welcome to the site, @VolcanoJ, glad you found us. Looks like you are on a path! Why not start a repair thread, as you diagnose? And, of course, if it's over your head..., consider sending it to a tech. Those are great amps, and putting them back into service in their original glory will be a great accomplishment - even if you have to send them to a tech. Enjoy the Music.

Welcome to the site, @MegaWatts. Lots of threads to peruse..., for sure. We love pictures - post a picture of your gear sometime!

And, for 2025, another James Bond is coming..., ? Or?

I don't care if people don't like or do like, Rambo movies. I for one, like them, and am looking forward to the next one, with this concept trailer..., some say the role get's handed off to rotating actors..., a la James Bond? The point being that audiences are not yet done with Rambo, and their desire for another in the series - even if Stallone wants to get out of the franchise..., or is too old for it, or..., Time gets everything, eventually.

Welcome @JRBARNES. So glad you found us. and, you are welcome!!, glad we could all collectively help drive you to refresh your gear... and, by the way, we LOVE pictures. Show us your gear..., and if you recorded your refresh, share your story... 😉 Start a thread in the appropriate forum (amp, preamp, etc.)

Welcome back! We have a user named AvGuyTX. But I think he's in texas. Not very prolific lately, but he's still there, I think - was that you - perhaps? What was your old handle? or email? I can try to look you up and see about connecting your historical posts to your new account... (no promises).

Welcome @Carver2000owner, great to have you here on TCS. Post a picture of your gear sometime. Or, why not start a thread on your 2000 recap? Always valuable to build up information for the next guy! And, of course, check out repair threads, as you need input. Again, welcome aboard.

Welcome @rssngrnnr_3 so glad you found us. Love it that you are the original owner of a pair of original Amazings! 😉 Post a picture of them! we love pictures. Again, welcome aboard!

Welcome, @ProAlpine, glad you found us. This website is a great forum of information and active fans - and it's searchable..., lots of historical information. As for this first request, I think the best way to approach this is to pull down the manuals for the C-2, etc., that you have. The configuration and wiring diagrams on how to hook things up are pretty good in the original manuals. You can find the manuals for download, at the top of the homepage for the website, in the "Manuals and Specsheets" pull down menu. Again, welcome!

Welcome @Brian K. Totten, glad you found us. I have a Denon 3802..., and nope, it does not compare (using my ears to test) with my C-1 and M500 combination(s)... Again, welcome. And glad you found us. Looking forward to more - and we love pictures!

Welcome to the site, @Rawi. Glad you found us. Carver amps should drive those speakers with no problem... What carver amps do you have? Post a picture. We love pictures !! 😉

Welcome, @DouglasT, so glad you found us. And love your history - Please tell us more..., like..., did you ever work on Lightstar? Perhaps do you have a Lightstar 1 schematic? ... We are always looking for missing docs from our manuals library, and that's one that I personally would like to find (for my Lightstar Series 1 amp)... Seriously, though, there are a number of options for the fan motor that have been posted over the years. I think they are still available, and someone with a recent memory can post a link - Or, I'll dig it up in the coming week. Or a Search in the search box on the Amps forums will also find it and other threads on how to address your issue. I should ask, are you looking for the entire assembly, including the fan blade? Or just the motor? Again, welcome to the site!

Welcome @BigB, glad you found us! Keep us posted as you put your 500 back in service.

With that TX-11, you will be able to pull in FM stations from miles, and I mean LOTS of miles, away. IF, that is, IF!, you get yourself an FM antenna. I have my internal home cable system connected to a big antenna in the attic, which pulls in FM from 200+ miles away. Probably get more reception, if I didn'thave 100ft of cabling, distribution boxes, etc, in the mix, but it works great for me.

Welcome, @tankdcrank, glad you found us. We love pictures, please post your audio rig sometime, and brag a bit!

I use the individual account, to feed content to my Roon account. Roon handles "everything, everywhere, all at once" Meaning Tidal doesn't know that I have this in 5 rooms, AND in my car streaming as mobile through my ARC extension to Roon. (Cost, I have the lifetime subscription..., so I don't pay for Roon anymore on a monthly basis). Roon manages all the devices, and Tidal is not aware (nor Qobuz). Ostensibly, MQA is dead, and not used on Tidal..., and no longer paying MQA licenses, this move was part of how they were able to lower their prices, recently.

human speakers has a replacement crossover harness they offer, that I opted not to purchase..., I may go back in and refresh the capacitors in the original crossovers..., but I didn't for now - mostly to do one thing at a time, and see if I can tell the difference with each addition/change. The other reason I didn't get Human Speakers replacement crossover is that it was $98, and I think I can update the caps for less than that, should I choose to do so. However, the Primary reason I didn't buy the replacement crossover, is that Huw has taken the design and changed it. He notes that the potentiometers are a waste, in his opinion, and so he has left them out. In my opinion, for this model alone due to it's unique design a la bose shape, I think it was valuable to be able to attenuate the front-facing output. to adjust the sound stage to the room.

OK, I was able to install the other drivers. I had a listen, and they sound wonderful! I'll have to do some comparison with the other speakers I have in the menagerie... But they can crank, loud. Right now driving them with a simple system setup..., you know, a Lightstar preamp through a Sunfire 600x2 amp 😉 Just to run them through their paces a bit. Here's some final pictures: The flat-wide face, faces the listener. the binding posts go to the rear. The angled smaller faces have bigger (8") bass drivers, to fill out the low-end, and deliver it via reflected sound to the listener, creating a sound stage. Most of Burhoe's designs were this way, There is a tweeter on those smaller angled faces as well, for the same purpose. The "shape" looks like Bose, but the design is clearly different. I have a little restorative work do do on the top and bottom of the cabinets. The photos show it very clearly - it's less noticeable in person. But this I can do. Note the tweeter on the top, driver's below. Those new OEM drivers from Human Speakers, sure look nice. And they are unique..., as noted earlier in the thread - the rear drivers are 2ohm, not typical 8"ohm - I believe unique due to the crossover. What are the pots on the back? One is to increase or decrease the high-end tweeter. It's a big fat potentiometer, in the Crossover design. the second pot is for attenuating the front driver and tweeter, allowing the listener to choose to balance the reflected sound-stage generating of the rear-facing speakers, with the front speakers that are directly positioned to feed sound into the user's ears. Which way is up? Looks like that one, below, is upside down..., actually, by putting the text on the binding post plates so it can be readable, the tweeters are up on the top. The grill, below, has the EPI logo on the wrong corner..., the oval hole in the masonite panel that the grill cloth is attached to, is wider on the woofer end..., so it's in the right place, but the factory put the badge on the wrong corner.., it may have been on upside down all it's life. the front facing driver is a smaller 6" driver. I replaced ALL the base and this front-facing mid-range driver - 4 (four) 8" drivers and 2 (two) 6" drivers total for the set (pair) of speakers. In the EPI community..., users that are in love with these and other EPI designs, swear by the inverted dome, oil filled tweeters built on a simple masonite plate. The magnet on the back of those masonite tweeters is as large as the magnet on the original woofers. The NEW (better, OEM-replacement) woofers from Human Speakers designed for these have a round magnet, not square - but guessing by heft, they are the same. Poing is, those tweeters have a powerful magnet, aboiut 3.5"x3.5"x1" controlling the oil-filled voicecoil. And, they still work, after ... I'm guessing ... 30+ years.

Welcome @JohnnyG, glad you found us! We love pictures of Carver and non-carver gear ... post and brag when you have a moment. 😉

Welcome, @marct, glad you found us. Post a few pictures! We love pictures of Carver gear!

Welcome @Ranster, so glad you found us. Many of us have unique journeys to our hobby, and yours is quite unique and different. One thing to start your project would be to go to the Tube Amp forum, and start you own "build thread." Many here could perhaps give some guidance..., post your project, pictures of the components you have now, the schematics you are following..., etc. No guarantees, but that's how I would approach your next catharsis project in your Bob Carver amps journey. Again, welcome!! and do stay and enjoy.

OK, back to this project. Lots of recent distractions..., some good some frustrating. The grills come off, attached by velcro - which is unusual for EPI of this era, they typically used white silicone caulk as glue to permanently affix the grills to speakers in manufacturing. I didn't have to wrestle these off. I pulled the old drivers out, and remove the old "gaskets" which is really just that white foam, that you find wrapped around new TT dustcovers to protect in transit. You might notice that there are two pots on the back..., one is to adjust by attenuation the high frequencies going through the crossover to the three inverted dome oil-filled tweeters. The second one is for attenuating the front panel output altogether. It's actually a fairly complex crossover. I'm not going to do anything with the crossover at the moment - right now I just want to get the new drivers in, and see how they sound. I find that the mdf in these old speakers typically is fraying or crumbling where the screws were driven in, w/o pre-drilling. What I do with this MDF, is try to "tighten up" the screw holes just a bit, as the screws always just seem to crumble it, like it's a triscit cracker or something. I rub off or cut back any of the "pulling" or fraying of wood chips, with a knife. so the frayed sawdust chips come off, leaving a flat surface to mount the new drivers against. Basically, this is pretty fragile, and very likely to "bust-out" when the new drivers are installed and the screws are driven back in, so I try to make it more solid, by using this technique..., I use some wood glue, and with a toothpick shove a bunch into the screw-hole, to and let it soak in. I wet the wood first, so the glue will soak in a bit beyond the screw hole, and attempt to hold the chips together in the area. I don't want to drillnew holes, as from two pictures up, you see the tweeter plate overlaps the driver, and this method strengthens the screw hole considerably. When done, the screw holes with the glue look like: When the glue dries, I will reinstall the drivers, turning the screws in by hand, carefully..., I've poked a driver foam with a screwdriver that slipped, before...,

Welcome @Rek. Glad you found us. Hard to say if the Carver pieces you have received were ever refreshed in the recent past or not. But in general, these items, if untouched since they were new, or if they were in a challenging environment (a dusty shop?), it's worth having them fully refreshed and adjusted back to new. Many here send their Carver gear to Greg ( @Nahash5150 ) proprietor of Nellion Audio, in Hersey, MI. I'm sure others will pipe in with other questions and recommendations. Again, glad you found us! There's a lot of information here, hope you post a few threads and stay a while. Welcome!

They restore/refresh, just like any other amp..., I recall that thread from @Carlton8000, or another thread, that he (or someone) recapped and refreshed the m240's he had. I've found that the "background noise" or a good portion of it, for me, was actually road noise, or noise generated by the car/cabin acoustics..., I only did one car audio build, when I was in my 20's..., so today, with all the sound deadening, and other things one can do..., I wonder if it's as bad. I have in my garage, a full system, brand new, that I picked up for my F150..., pioneer head unit, infinity cappa speakers for all four doors, and an infinity kappa sub... It's one of those projects I keep putting off. But I know that one thing I must do is put in a lot of sound deadening in the doors, where there's lots of flex from the increased throw and air movement of those Kappa's. I don't think I'll go so far as to deaden the floor of, I'm too lazy to pull out the seats, and carpet, to add it.

I don't really know. KLW was an external partner..., not much on them. I do think that the early plain amp designs, like the m240 had some indirect "Bob" fingerprints on it - but that's just folklore, at this point. Maybe @Ar9Jim can ask Bob sometime?
