I have a pair of trade-in black Carver 350 mono amps for sale. The price is for the pair. They have been tested and sound great. These amps are amazing values and can drive any speakers. They also run far cooler than any other tubes amps so the output tubes had a 10 year warranty when new from the factory. They are sonically adjustable and you can make them warmer of more detailed to match your system. -

From the Carver site:
Bob increased the energy storage three-fold, compared to the previous 305. Utilizing Tung-Sol KT-120 output tubes, the Crimson 350 will bring new life to your music library with its extended dynamic range and abundant output power. (KT150’s are no longer available from Carver as Bob clearly preferred the 120’s) These KT-120s are rated for 75 watts of audio output each, and this amp has six of them for an easy 350 watts RMS. These tubes are one and a half times as powerful as the ubiquitous 6550 or KT88. According to Bob, they “sound beautiful, sweet, and so incredibly delicate, that once again, it is difficult to believe. But it’s true. Honest! I love their unique shape. The only thing I don’t like about them is that it’s difficult to see the filaments glow in the dark. The plate structure gets in the way.”
Using his own transformer design, the Crimson 350 delivers 350 watts into 8 ohms (400 watts into 4 or 2 ohms) of pure sonic ecstasy, regardless of the loudspeaker’s impedance vs. frequency. The new, heavier output transformer delivers enormous power through an increased turns ratio, with two extra interleaved windings, each bifilar wound on a core of Adamantine steel and now with an upgraded pure nickel center section. The secondary’s are wound with oxygen-free copper wire and 98% pure silver wire for the critical internal interconnections. As Bob says, “I could go on and on, but I will say that the bandwidth of this output transformer is an amazing two hundred and fifty kilohertz - that’s a quarter of a megahertz!” This extra wide bandwidth ensures perfect stability into one ohm speakers, including those that possess almost impossible-to-drive impedance characteristics! Even the one ohm Apogee Scintillas, or any other speaker that dips down to 0.75 ohms, for that matter. Martin Logan electrostatics, for example, whose impedance drops down even lower than that at very high frequencies (to about 0.5 ohms). This amplifier can drive them all with aplomb!
The Crimson 350’s bias is easily and simply adjusted using a single control, making it unnecessary to adjust the bias individually for each output tube set. The DC restorer circuit, an exclusive to Bob Carver designs, keeps the output tubes running cool, prolonging their life to beyond 50 years! Prior to the advent of this feature in Bob’s amplifiers, other amplifiers operated their vacuum tubes at a very high idle power in order to keep the distortion low, frequency response extended, as well as for a host of other reasons, related to amplifier performance. And they still do. The downside of doing so is that the tube life is drastically shortened, about three to six years at the most. Worse yet, tube performance begins to deteriorate as soon as the amp is turned on, gradually (and insidiously) robbing the listener of sonic pleasure. In addition to extended tube life, thanks to this invention, there is also no need to purchase expensive matched tubes for the Crimson 350.
The screen voltage is regulated on speech and music to a difficult and almost impossible to believe 1%, and the bias regulator has been redesigned to almost perfectly restore the DC component of the incoming audio signal. Nothing else can even come close to this performance.
Another significant feature of Bob’s design is its ability to “listen to the room,” sometimes referred to as the ‘speaker-microphone effect.’ Facilitated by a special current feedback loop, it allows the amplifier to ‘hear’ the room’s reverb, along with its unique sonic signature. Each room plays its own tune, and this amp 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. Think of it this way, the room becomes an integral part of the music in a way no other amplifier allows. The sound is more majestic, more realistic, and the soundstage is larger and more compelling than it would be without this unique, spooky and strange ability. To be sure, all tube amps do this in small, almost minuscule amounts (Harry Pearson noted this long ago), but this amplifier does it to a great extent and in a rather complex manner by very intentional and special design. This phenomenon is impossible to achieve with normal solid-state amplifier designs, whose low source (output) impedance effectively shorts out the speaker’s ability to accomplish this feat.
Finally, Bob has also added a set of XLR inputs as well as the RCA ins from the previous products.
The Crimson 350 brings added clarity, life, and presence to any existing system and loudspeakers.
