Ive seen on ebay a few deals on the carver amps.Some would say "magnetic field"others would say "high current"amp.What do these specifications mean.Dont mean to be ignorant i just dont know the differences between these and regular power amps.

His amp owners manuals give a good description of the magnetic field design. They are supposed to be the closest thing to "tube" sounding in a solid state design. They are high current capable, which means they will drive the most inefficiant speakers with ease. I have owned 3, TFM-25, TFM-35X, and the TFM-15. As someone commented once, they will drive nails. Great for Bose 901's, Infinity Reference 2.5's, these demand ALOT of power. I have since sold mine and moved up (to me) the food chain to Rotel. -
I think Magnetic Field is merely a term used by Carver to describe the power supply design that was more or less unique to his products at the time.
Perhaps a tech expert will chime in, but I think that the Magnetic Field Carver amps use a type of power supply that keeps the rail voltages just slightly above the voltage required at any given level (within the amps capabilities, of course) to reproduce the audio signal. The concept is to minimize voltage drop across the output devices in order to reduce the heat generated and also to minimize the need for brute force power supplies compared to conventional designs.
Not exactly sure if they are the same, but I think similar, the newer Carver amps use the term Tracking Downconverter instead of Magnetic Field.
Again, if I mucked it up too badly, I hope someone will clear it up for the both of us.There are some things which are impossible to know, but it is impossible to know which things these are. :scratchhead:

does anyone know if this is a reliable 2 channel amp? how many watts per channel? and would it be a good addition to my RSX-1056 to drive my front speakers? any help as to magnetic field would be appricated.
thanks paul -
I have a problem which I haven't been able to solve yet.About two weeks ago,I put one of the B&W 685's on a shelf,very close to the dvd recorders and satellite receivers.685 was not connected to the receiver(amplificator).After a while in the same day,the satellite receiver started getting locked.Then...17 January 2010, 18:13 Sunday -
Planar Magnetic Transducers
A planar magnetic transducer, also known as a planar driver, is a type of loudspeaker driver that uses a thin and lightweight diaphragm with an embedded conductive coil to produce sound. It operates based on the principles of magnetic induction. A planar driver consists of the below:- Diaphragm: The diaphragm of a planar magnetic driver is a thin, flat, and often rectangular or circular membrane made from a lightweight material such as mylar or a thin metal

Magnetic Shielding
Magnetic shielding is a technique used in loudspeaker design to prevent the magnetic field generated by the driver's magnet from interfering with nearby electronic devices, particularly CRT (Cathode Ray Tube) displays. When a loudspeaker's magnet is positioned close to a CRT screen, it can distort the image by deflecting the electron beams in the CRT, causing color shifts and geometric distortions. The concept of magnetic shielding was developed to address this issue...21 July 2023, 17:49 Friday -
I've heard Thomas say that the effects of a nearby unshielded midrange on a CRT television depend entirely on how far away it is from the TV, and how well shielded the TV itself is.
Is it possible to test out the TV set itself without having a built speaker? How strong of a regular magnet...
