Hello Everyone,

This auction is for a used, but in great Condition Carver M-400a Magnetic Field Power Amplifier.  This unit belongs to my friend, was purchased about 15 years ago and was recertified in 2004 ( I do have the recertification paper work that I can send you as well).  It has been used a few times after that and functioned just fine.  However, it hasn't been used in the past few years and I dont have a way to verify it's functionality now.  Cosmetically, it is in great shape, just a few surface scratches on the body, but nothing major.  All the ports and led's seem intact.  

Here is more information that I found online for the unit:  



The Carver M-400 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 may be used as either a single-channel or dual-channel unit with 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: 201 watts per channel into 8Ω (stereo), 500W into 8Ω (mono)

Frequency response: 20Hz to 20kHz

Total harmonic distortion: 0.05%

Damping factor: 150

Input sensitivity: 1.5V

Signal to noise ratio: 100dB

Weight: 12lbs

Finish: black anodized

Year: 1980


This is a Buy It Now Auction set at $300.  Shipping and Handling is $20 via USPS Priority Mail with delivery confirmation to anywhere in the continental United States only.  I am a very reasonable person and open to all offers, so please send me an offer and it will be considered.  This item will be packaged securely and safely.  I ask that the winning bidder please pay within 2 days of auction close and I do prefer payments by PayPal.  I do check my ebay auctions routinely throughout the day so if you have any questions or concerns please ask me and I will get back with you asap.

Normally, I do accept returns for the items I sell on ebay, but because I can't verify the functional condition of this item, I can't accept returns on this.  I do apologize for the problems this causes, but I am describing the item the best way I can from what my friend and I know.  So it is being listed "as is"  Sorry again, but appreciate your understanding.  Good luck.
