This amplifier has been serviced, upgraded, and recalibrated. All electrolytic capacitors, power caps and all small caps, are replace with higher rated versions suitable for use in a MK II or MK II opt 002 upgrade. It is in excellent working condition ( Video at https://youtu.be/CbMGs1MSLyw ) Upgrades include gold plated RCA input jacks, gold plated 5 way binding post output jacks, idle bias pivot (also called fulcrum pias pivot), shut off thump fix, and multi color power meter LED display (purple on status, 3 rows of green, then 1 row of yellow and finally 2 rows of red). The amp was also adjusted to facory settings. Previouely tested to full power with speakers capable of handling the power. The video only gets the power indicators to about half as the speakers I had handy to shoot the video do not have the power handling capabilities for this beasts output. Original units in need of rebuilding, and due to capacitor age most need rebuilding, cannot produce full power like this rebuilt and upgraded unit can. Units that have not had all the electrolytic capacitors changed will not only have reduced output but are likely to stop working once one of the many capacitors gets far enough off value. Case is good condition with a couple minor scratches This amp has been a cherished part of my audio system. I love the amazing Carver sound but now have two Carver M-1.0t MKII opt 002 with double the power so this amp is now excess to my needs. The wife told me to clean up my listening room and get the stuff I don’t use out of there Description The Carver M-1.0t power amplifier is unique in electronic and mechanical design. It is designed to provide the listener with a source of voltage and current to drive high fidelity loudspeaker systems. It has a very high efficiency of weight, size, heat dissipation and cost, with very low distortion and noise. Intended for use in the home high fidelity music system, it is capable of extremely high power output with excellent loudspeaker load-drive capability. The design has been optimized for home audio applications in which high power excursions are necessary to prevent distortion of dynamic transients, while bulk, weight, heat and price considerations have traditionally restricted use of such devices to a small number of consumers.Efficiency has been dramatically improved by techniques which substitute electronic control for the large quantities of bulk copper, iron and aluminium required by conventional designs.This control factor in the power supply section is augmented by amplifier design which dissipates power as required on signal demand so that heat sinking and quiescent dissipation are held to a minimum. Distortion components typical of the more efficient traditional class AB designs are virtually eliminated by use of sliding idle current.Comprehensive amplifier and loudspeaker protection is provided by conventional means, augmented by the controlled power-supply, which will shut down under unsafe conditions as determined by a separate sensing network.Analogue computer techniques are used to monitor operational parameters and override the normal power supply control function in the event that operating conditions become unsafe for amplifier or loudspeakers. Power output: 200 watts per channel RMS into 8 ohms, both channels driven, with no more than 0.15 percent total harmonic distortion, 20 to 20,000 Hz and 400 watts per channel into 4 ohm speakers.350 watts per channel RMS into 8 ohms, both channels driven for musically significant time periods.550 watts per channel of Dynamic HeadroomCan be bridged as a mono amp at 1000 watts into 8 ohms. Amazing for driving a subwoofer that will move you!Noise: 100 dB, IHF A weightingHarmonic distortion: Less than 0.15%Input impedance: 100 K ohmsLoad impedance: Recommended for driving impedances from 2 to 32 ohmsDisplay ballistics: 1 millisecond attack, 1 second release Dimensions: 3-3/4 High, 19 wide, 13-1/2 deepWeight: 19 lbs. _gsrx_vers_1634 (GS 9.6 (1634)) On Feb-06-24 at 17:55:08 PST, seller added the following information: Sorry for the video of the M-400 in the pictures. I copied and updated an auction from a ways back of my original M-400 amp and missed deleting it when I made the listing for this updated, upgraded M 1.0T. EBay will not let me delete it. The video link in the text is a video of this specific M 1.0t amp and there is no M-400 associated or included in this auction.

Carver M-1.0t Stereo Power Amplifier Works ( Read Below) This is tested and working. We got it with the screws tape to the top. They need to be put back into place. One of the speaker terminals is broken and will need to be replaced. Its an easy fix. DescriptionThe Carver M-1.0t magnetic field amplifier was released in June of 1986.The original version of the amplifier had inverting outputs, that is the right channel output is inverted (180 degrees) from the left channel output.Starting at serial number 4500 (or 70100000), the amplifier was redesigned to include a stereo/mono switch which inverts the right channel for bridged mono use.In normal stereo operation both channels are in phase.SpecificationsPower output: 200 watts per channel into 8? (stereo), 1000 watts into 8? (mono)Frequency response: 20Hz to 20kHzTotal harmonic distortion: 0.15%Damping factor: 9Gain: 27 dBInput sensitivity: 1.75VSignal to noise ratio: 100dBDimensions: 95 x 483 x 343mmWeight: 8.6kgYear: 1986

Bob Carvers design and engineering Low distortion the doesnt go up with volume, few makers achieved this Bob was pioneer in short no wire connection that resulted in awesome sound and music recreation or original recordings. I like Adcom and Onyko amps, but Carver out did all competition in its price range. This retailed around 500 and still holds that value as parts needed to keep working great are readily available on Ebay. Amp has scratches and marks throughout as this has been around about 40 years. Powers up and pounds as it should has on off switch on front ( some Carvers do not have front power switch). Priced to sell and enjoy, may need recaps sometime in the future as all vintage amps do to keep sound clean and distortion free. Working great as of last use. Wont disappoint. I have never open it up. No need so far. Listed below market value to sell. 200 WPC at 8 ohm loads.

Great condition and works great.

Carver M-1.0T Magnetic Field Power Amplifier, Beautiful Condition. Purchased it about 2 years ago. Used it as my main audio amp for about a year. I love it and hate to part with it, but re configured our living space and I have no more room for a large system. That is the only reason for the sale.

Carver M-1.0T Magnetic Field Power Amplifier, Amazing Condition. Condition is Used. Shipped with USPS Ground Advantage.

SN#07158 Unit powers on, does not blow fuses, bottom row of LEDs light up. Right channel has 11.5 VDC on output, left channel puts out slight buzz on speaker. Looks all original. Black casing is scrathed up, silver faceplate looks pretty good.
