CARVER CRIMSON 275 TUBE POWER AMPLIFIER


Financial restraints require me to dismantle and sell my high end system, a featured piece of which is the Carver 275 Crimson stereo tube power amplifier.


I am the original owner of the Crimson 275 which was purchased last march from Glen Poor’s audio video in Champaign Illinois. This amp is simply state of the art in its price and power range and is in pristine condition with only about 20 hours of use in my second system.!  The warranty includes 5 years on the tubes and is tranferrable (see below).


PLEASE CHECK MY FEEDBACK!


From Carver:


Over a full year in design, complete with innovations never dreamt of at this price point, we were nonetheless shocked to see how closely the Crimson 275 performs next to our 350 series monoblocks which sell for $9,500/pr.!


Due to the unique design, all the components in the amplifier undergo much less stress than in conventional designs. Due to the efficiency of the concept, our transformers can be lighter and despite Bob Carver specifying esoteric steel for their cores, it helps us sell a $4000 amplifier for under $3000. Transformers are traditionally the most expensive component so if there’s no compromise in performance, this is a genuine benefit.



5-YEAR TUBE WARRANTY!


Although Bob Carver has been demonstrated to be at the leading edge of amplifier design, introducing, through the years, patented and unique approaches to efficiency and performance, many engineers believe power supplies may be one of his great strengths. As with his legendary SunFire tracking power supplies, the bottom line is that you may expect our amplifiers to outlive any other brand, and our extended warranties underscore that fact.



We warrant the Crimson 275 for a full five years; that’s the amplifier and the tubes! We love the fact that our finest competitors warrant their tubes for three months. It’s all about economics. If your tubes tend to fail, limit the warranty. A manufacturer has no option; they must. Since our tubes last for years, it costs us nothing to be heroic.



There is a meter on the front of the amplifier which can indicate the health of the tubes — get a bad reading, get free tubes! Aside from the extended circuit and tube life, it’s the sonics that blew us away. One of the reasons for this is our proprietary use of two separate feedback loops. One, typical of what you’ll find in many fine amplifiers, ensures stability and linearity. But the other is quite fascinating.




An amplifier that actually listens to the room.



All loudspeakers generate voltage as they play. It’s generated from the driver movement necessary to reproduce music but also all loudspeakers technically “listen” to the room. Did you know that the loudspeakers in prisons are also microphones? It enables the authorities to monitor the prison’s pulse in real-time. All loudspeakers are microphones. You might not want to use one for recording but conceptually, they are microphones in reverse.



Loudspeakers are electric motors. Electric motors all kick voltage back to the power source whether it’s a loudspeaker, a refrigerator or an electric drill.  Manufacturers of line conditioners have a point. Your refrigerator motor not only adds noise to the AC line, they actually send electricity back through the wall outlet. We call this Back-EMF.


 


With a tube type amplifier, when back EMF appears at the output terminals, to the loudspeaker the output transformer’s secondary becomes a primary! The back EMF enters the amplifier through the transformer and affects frequency response downstream. With ordinary tube type amplifiers, speaker matching becomes critical. Our amplifiers are load-invariant. Through decades of experimentation and some pretty heavy mathematics, Bob Carver has been able to use the Back-EMF to increase efficiency in the mighty SunFire subwoofers, and to improve the soundstage and openness of his full range amplifiers.


 


This is done in a unique fashion, and, as in the case of our extended tube life, unique to our products. The amplifiers listen to the room through the loudspeakers and preserve a large soundstage. It took literally decades to get the circuit right without creating artificial coloration. If you’re concerned about naturalness, consider that Harry Pearson, the founder of Absolute Sound Magazine, noticed this phenomenon, pointed out to Bob (who already knew about it) and kept our Silver Seven amplifiers as his personal reference for years. Dick Olsher from Stereophile Magazine called this series the most important tube amplifiers in decades.


 


As with our more expensive amplifiers, Bob employs his unique twist on a DC restorer circuit which has two main benefits —lower distortion without dissonant side effects and extended tube and amplifier life.Power to Drive Almost Any Speaker and Full, Sweet, Warm Tube Sound That Makes Music Sing: Bob Carver Crimson 275 Stereo Amplifier Features Incredible Warranty and DC Restorer Circuit


There's nothing like the sound of tubes – a fact iconic audio designer Bob Caver knows as well as anyone. Responsible for some of the most revered valve designs in the history of high-end audio, Carver marries beautiful, sweet-sounding tube performance with stop-you-in-your-tracks value in the Crimson 275 Stereo amplifier. Inspired by its Crimson 350 sibling and hand-built in the U.S.A., this gorgeous powerhouse is fueled by the same Tung-Sol KT120 tubes as Carver's monoblock amps. It plays with a richness, fullness, warmth, and boldness that takes you to the edge of the studio (or concert) stage.


Nominally rated at 75Wpc, Crimson 275 Stereo actually delivers 100RMS/channel into four ohms – enough power to let you hear (and feel) your music. A DC restorer circuit, exclusive to Bob Carver designs, keeps the output tubes running cool and prolongs their life to a near-unbelievable 25 years. It also means you will never need bias adjustments. No wonder 275 Stereo comes with an ironclad five-year manufacturer's warranty on operation, parts, and tubes!


Akin to the company's Model 350, Crimson 275 Stereo listens to the room – a trait often referred to as the "speaker-microphone effect." Facilitated by a special current feedback loop, the amplifier can hear the room's reverb and unique sonic signature. By design, 275 Stereo uses the speaker as a microphone by using the speaker in reverse (the theorem of reciprocity) to listen to the room, thereby allowing a portion of the room acoustic to be expressed through the main speakers. As such, the room becomes an integral part of the music in a way solid-state amps do not permit. The resulting sound feels more majestic and realistic, and the soundstage larger and more compelling.


Stellar stability with any pair of loudspeakers, transformers with interleaved windings on adamantine steel with pure-nickel center sections, a ridiculous signal-to-noise ratio (110dB) that bests that of most transistor amplifiers, and a built-in meter on the front panel further raise the stakes of a tube amplifier whose features, quality, support, and sonics belie its price. Our 100% Music Direct Satisfaction Guarantee gives you every reason to audition it in your own home.


Carver's Unique U.S.A.-Made Output Transformer and the Solution to Magnetostriction


For some time now, Bob Carver has been working on a novel approach to manufacturing an output transformer. All transformers suffer from magnetostriction. This occurs when transformer noise is caused by a phenomenon that then causes a piece of magnetic sheet steel to extend itself when magnetized. When the magnetization gets taken away, it goes back to its original condition. To minimize the effect, quality transformers use a special steel alloy. Bob has come up with an alloy that, along with its magnetic nature and his proprietary winding technique, increases the efficiency and provides his company two options: Increase the power by using a larger version of the new design and sell the amplifier for $3,500 with a 150Wpc output. Or, the path Carver chose, use a smaller and lighter U.S.A.-made version that still provides up to 90Wpc and allows the price to be kept lower.



TRANSFERRABLE WARRANTY


Regarding the five year warranty, the following is from the 275 owners manual:


   “The Crimson 275 is covered by a five year limited warranty on parts AND VACUUM TUBES. The 5 year warranty is transferable from the original purchaser. The new owner must receive a copy of the original purchase receipt from the original owner in order to continue warranty coverage.” 



The first photo is of the actual unit being sold and the second is from the internet. 

I will ship in the original factory packing with the owners manual and the receipt.  The buyer should add $100.00 to cover audiogon fees. PayPal fees and shipping (the unit is very heavy).
