B-Man

Welcome !! We're always happy to see a new face.

Yep, I remember those pics. RobertR and Bob hammering out the crossovers. I believe you are correct - that was at the Sauter's residence in southwest Florida. Gotta love the purple Christmas tree !!!

Welcome to the Carver Site bobpep! We all look forward to your upcoming rebuild. And to your next acquisition. And yes, there WILL be another piece of Carver gear in your collection... Trust me. 🙂

Welcome !! Great to have another tinkerer on the forum. I wouldn't worry about the ESR on those caps. Pull one of the old ones and see how it measures - in ESR and actually capacity terms. I'm curious. I never measure them when I yank them - I chuck them into the trash, install the new, burn it in and place it into service.

Welcome !! Very happy that you are willing to share with us. Post a few times and then post some pics.

I never had the opportunity to audition their home line but I used their automotive line back in the 90's and they were superb. I lucked into a crazy deal - Sound Advice in Tampa received a palette of their 6 1/2" component speakers that were in a warehouse that had a roof leak. The boxes on the top of the palette were water damaged - the rest were stained so the insurance company wrote them off. I bought 4 sets of their highest quality units at the time for $100 each. It seemed crazy because all of the components inside the boxes were wrapped in plastic and suspended in styrofoam packing - nothing got wet. I installed and removed those speakers in 4 different trucks and two cars. I still have them in a box somewhere. The only components I've ever heard that compare were units made by Focal. I'd love to hear those you have - enjoy !!!

Welcome !! X2 what Mark (Daddyjt) said - the M500 amp would be a better match for the Klipsch. Talk to Nelion - he may be able to hook you up. Enough of the nice crap - where's the PICTURES ???? 🙂

If you look into the requirements of construction you mention for those Skil tools you will see that the Crimson amp does not comply with that methodology. That is why they would not receive a UL certification in their current implementation.

Welcome !!! You can't do better than Nelion for your audio needs - even if we are a bit biased here... 😀 Whatcha flying ?

Yeah, screw all that welcome Chris crap - let's see some pics of the SS !!!!

I agree with your EG thought process but unfortunately UL, CE and others disagree - and I bet the legal review of any issues would fall back to looking at those agency listings, electrical codes, etc. I'm not arguing for their thought process - I'm more interested in what Bob Carver Corporation is going to do, if anything, about the situation. I saw a note that said Bob agreed to pay shipping both ways to have anyone's amp re-wired to utilize a chassis ground at no charge but there isn't any mention of this on the Crimson 275 web page.

I'm glad you are still here. Technically, yes - you are at some level of risk. Who among us hasn't been "bit" at least once by our friend the electron? Is it likely you will be seriously injured with your knowledge and experience? No. They are talking about it from a mechanical failure inside the amp perspective. I'm not defending their stance, other than to say that if someone bought one and it had a floating screw inside (ironically that is what happened with the retail unit they purchased to test) that has the hot side shorted to the chassis it could end up being a bad scenario for the end user. Not likely fatal but a definite issue nonetheless. A lawyer's paradise for sure...

Yeah, those idiots obviously don't understand grounding and why and where it is applied. I shake my head at stuff like that - have they looked at the two prong power cords on 99% of consumer electronics sold in the US? Unreal... EDIT - After making more time to read the thread they are also bringing up the true "safety" grounding aspect. As in if there is a wire break, a switch failure, etc. how the lack of insulation inside or the lack of a chassis ground can create a dangerous situation for the end user. From a CE or UL perspective this can be a liability issue. I am curious to see how it is addressed, if it is at all.

I'm not trying to be a dick here but I want to throw out two things about the Audio Science Review web site review of the Crimson 275: 1. Amir is a sound, knowledgeable guy who has tested untold numbers of amps, etc. He has the knowledge and equipment to test amps properly and is a Bob Carver fan in general. 2. The overall tone of the site and the review of the 275 is that it does not meet the specs that are printed in the documentation. That is the main beef they are talking about. If there is an issue with his testing method it should be addressed. If not then it really looks bad for the Crimson 275 when judged by the published specs. I personally like how both of mine sound but the focus of the review is that the claimed output power is 75 watts into 4 or 8 ohms - and that appears to be a great stretch when reviewing the results of his testing efforts. The amp he tested blew the power fuse well before achieving anywhere close to the claimed power levels. The other area that is causing criticism are the tiny output transformers - they saw the 15 watt labels and immediately jumped to their own conclusions. To be fair to them all of the tube amps they have tested over the years that do produce 75 watts per channel are much heavier because of the large power and output transformers. For example, the McIntosh MC275 delivers 75 WPC, into 4, 8 or 16 ohms, 20-20KHZ, 0.5% THD max, 105db S/N ratio. It weighs 67 lbs. In comparison the Crimson 275 weighs 19 lbs. You can read Amir's testing and evaluation here: https://www.audiosciencereview.com/forum/index.php?threads/carver-crimson-275-review-tube-amp.29971/ Unfortunately the unit he received had a loose screw floating about inside the chassis. That could have presented itself as an issue if he had not found it during his inspection of the amp. I would be interested in seeing what the actual power and distortion measurements are when tested "properly" while using the full 20-20KHZ audio bandwidth, presented like the McIntosh specs I mentioned earlier.

These kids are pretty impressive. Watch the drummer when he drops a stick.

Welcome Long Ear !!! We are glad to have you on board. Please share some info about your system - including the non-Carver pieces. We appreciate all audio-related stuff around here.

Welcome !! We're glad you found us !!

Welcome !! Get busy posting and in no time you can share some pictures of your system. 🙂

Holy thread resurrection Batman !!! 🙂

Some things can be generic - replace all of the electrolytics for example. After that it starts getting more complicated. Do you have the gear to measure performance? Most of the electronic parts will last indefinitely - but there may be something degraded that is technically working but not delivering it's full capability - which might be measured as distortion, noise, etc. with the right equipment. Parts availability and substitutions change so frequently that a list is only accurate on the day it is created.

Welcome, fellow Tennesseean !! I'm south of you, 30 miles south of Knoxville. Those speakers are well regarded here. Plenty of information and experience to help you on your journey. Once you get them sorted out you may want to experiment with feeding them more power but that Adcom is a nice unit and may prove to be completely adequate. Has your 5500 been refreshed? Big caps replaced? It could probably stand for some soldering iron love.

Welcome !! Nice system set-up. I've wanted a set of 10Bs for a long time. I love my Polks - they work well with my M1.0ts. The noise might be reduced when Greg replaces the power supply caps. If he finds it's unusual you can rest assured he will get to the root of the issue. Good news is if it has been doing that for 30 years and it still plays it hasn't hurt the mag coil.
