That's about roughly when I started having trouble with mine, around 300 hours or so. It started with a loud "PoP" shortly after power up, I was in the other room and heard it quite loudly through the speaker(s.) Amp still sounding fine so shrugged it off. A couple days later noticed the meter was only reading 20ma or so and when I tried to re-adjust the bias it would max out at around 55ma? It's a little funny, I've seen you mention before that you had the "review" amplifier- I wonder which one of us actually got that amp as I supposedly bought that amp too. I don't really care if I'm being honest I just jumped after it because of the $500 discount that was offered at the time, which he ended up extending to all new amp sales anyway. Jesse

I wanted to say thank you for taking the time to look at and fix my amplifier- I've had it back in the system for a few days now and it appears to be working perfectly again. As much as I enjoy the 275 amplifier the 285 is head and shoulders better IMO; it has the warmth and tubyness while at the same time solid state like bass and clarity and good high end which by comparison seems pretty rolled off on the 275. Anyway, thank you for stepping up and offering service for this great amp- while frustrating that @Ar9Jim Jim Clark ducked out it is understandable and I don't harbor any hard feelings towards the guy.

Has anyone heard from @Ar9Jim Jim Clark? Seems he hasn't been to the site for a couple months and the link here is no longer working?

You know what I think would be awesome is short video review from Bob Carver. Get him in front of a camera with one of these amplifiers and let him give his pitch. I have to admit the short video of him telling a small crowd that the 275 was one of his best designs was the tipping point for me when I made my initial purchase.

Nice Celica! I had a '76 decades ago fun little car

Welcome! You have a couple of very nice amps, some of Carver's best work I think. Curious to hear about the rest of your system(s) we like pictures

Yes, once you get started it can be impossible to stop! Welcome to the forum, nice selection of speakers- we love to see pictures

Welcome to the forum! Have you considered one of the newer Carver tube amps? They sound excellent with Klipsch speakers.

It's a real shame if the 275 cannot continue on in some form as it really is a wonderful little amp and lets face it a lot of people simply cannot afford to wet their feet with a $5k amplifier.

So who is building these amps?

It is a very difficult task too many variables like room acoustics, equipment matching, type of music, how loud you play and of course personal taste. It does get me that almost every single review seems to be positive and the unit being reviewed is almost always a "must have." I went through too many reviews to count when buying headphones recently before I decided to do my own in home trials very few online reviews matched up with what I experienced personally.

The Receivers? I personally prefer the original still have a couple in use. The TGR-3 was built in China after Bob Carver sold the company to Elan. I found the newer models to be a bit more black or neutral sounding where the older units seem to have a touch more flavor not by a lot but noticeable. All in all they are very similar and both decent units.

A guy turned me on to the Hospital grade cords awhile back as a cheap alternative to the fancy cables, the plugs are tight fitting and seem to be good quality. Other generic cords can be found online for about what it costs to ship them. Factory Sunfire cords are a 14ga 2-prong but a 3-prong works just fine. https://www.ebay.com/itm/325455731917?hash=item4bc6ac5ccd:g:~JIAAOSwRJJjknKo&amdata=enc%3AAQAIAAAA0DLe4ohlMddNeiZ%2FYNiH7%2FOwT8QP2sz5FcS%2FQ0i5l%2FyidllsHGKm8bY8X9uzF8K3nnctt6GWsk%2FsdrNKyHJAv%2Bw6OeNfIf0%2BzyLxfBOYoqnCRTQVu00WWANpoY6aDwjF7bp6jfMiDbsECGVF3ut%2FYzBLRlloGnHdCAA8yykzAyW%2FTO7WGfAEs29fvHSWZBHweEoDnhI2plAnkH68Q%2Fr2r652wLeMISnKJftpyMcLc0UNF1t9gtPmThCLaUzy0X%2FBf70qFytYzk%2Fj%2BDqI9hC%2BKq0%3D|tkp%3ABk9SR5zJ0M_5YQ

The Sunfire remotes are pretty much the same TG-II through TG-5 which include the first 3 receivers I believe the IV & 5 have a couple pro logic buttons that the earlier ones don't have but all basic functions and controls are the same. The very top one in the picture above is the correct remote and will work on both units, once you have a working remote you can buy a universal and clone / copy it pretty easily.

I know for a fact they can deliver that power one channel at a time seen it with my own eyes many times at Bill Flannery's on his test bench. As for all channels driven? Don't think that's physically possible- I'm sure there's an upper limit on total output power that gets divided amongst all channels not sure what it is on those amps. Bill once told me the Sunfire Ultimate Receivers maxed out at around 575 watts total output no matter how you slice it; roughly 290x2 or 85x7 I'm sure the amplifiers are probably the same way.

Your space is huge-- you trying to fill the whole thing or just get sound in one area? I don't think any "home" speaker is going to fill that space.

Just go with the big boys from Klipsch Pro:

It seems every speaker I've owned has had their pluses and minuses, have yet to find one that is perfect. Even my current Franken-Klipsch creation as good as they sound now it took the right equipment matching to bring out their best.

Know exactly what you mean my speakers are the same way 15" Eminence drivers with 16x9 Tractrix horn's and 2" exit drivers with 3" voice-coils and magnets the size of 12" woofers these guys just loaf along. I've been playing with various Klipsch speakers for 20 years now and room acoustics and equipment matching are critical to getting a great experience very easy to get it wrong and have it sound bad or harsh but when you get it right it is very rewarding.

Very cool, thanks for sharing! I just saved the full playlist to listen to on the main stereo later today:

Not sure about your ability to sell others can chime in on that as to value physical and working condition are going to be big variables also if you have the original box and manual that helps. Clean it up, plug it in and test it, take some pictures and report back if you can. If its clean and works as it should I would think $500 would be a good starting point?

I have been using the KT-120's since they've arrived-- they run considerably cooler than the 34's do and my AC unit has a hard time keeping up during these hot summer days. First thing I noticed when I received the 25 was that voices and certain guitars seem to be pushed forward compared to the 120's and the 34's seem to be just a tad lighter in the bass. Overall balance is different, I like both too. That being said almost everything is different in my system now (new DAC, Pre and speakers) and I'm dealing with a broken back so haven't been able to do much right now, part of the reason I've been online so much over the last month. Once my back is a little better and temps drop a bit I plan on playing with the stereo some more.
