    That model is supposed to be the best sounding TFM amp but, there is a fix that it requires that I can't explain because I don't understand that kind of stuff! If you want Carver technical info you should ask the guys at:http://www.thecarversite.com/ but don't tell them who sent you! That amp has big watts & lots o' headroom.

    My question is do these TFM amps really put out rated power?

    And why are they so light? The TFM puts out around 500 wpc @ 4ohms and weights around 30lbs? Doesn't make sense to me, could someone explain?

    It's the best sounding amp, IMO, that Carver made. More than enough power for any of your needs.

    I have never listened to the TFM-45, but I have the TFM-35, and it is more power than my SDA-1A's can handle. If I turn the gain up to more than 50% of full value I will blow the 1A fuses protecting the tweeters in my speakers.

    I am unsure if they hit rated power, but having heard a 35 and a 45 they sure do put out a lot. You will go deaf before you hit clipping in the 45.

    Very nice sounding amp the TFM-45. I would suggest getting your ears on it first though. It has that Phase Linear/Carver sound. Some love it some don't(I love it). On SDA's they sound great so you should be good in either case.

    At 50 - 90 watts output, my TFM-45 that I aquired from thsmith and already reworked by Roland makes listening uncomfortable without percieved distortion. I use this amp and a NAD 2600 and like them both with no problems.

    It's about sound not power, but I don't have time or resources to roll tubes.

    Tons of information if you search. And there are plenty of followers for the amp so as long as you get into one right, you can dispose of it fairly quickly without losing your shirt.

    It's due to the power supply. Without going into lots of detail, the original TFM series uses the Magnitic field power supply. The major weight differance is the transformer.

    Here is some good reading to start out with,

    I've heard that the build quality of these Carver amps is not the most 'robust' but some of you say you've had no problems with them. Some people love that Carver sound, others not so much. I've only heard it a couple of times and it didn't jump out at me but was certainly good enough to think about buying one and spending some time with it for a more informed assessment.

    I've run a 45 for the last few years with no issues and sent a 35 through Rita's shop about 5 years ago. They have a nice sound and are great bang for the buck solutions. I've never read what they do on a bench, but have never read that they fudged the numbers. As others have said, you'll never reach the limits of the 45. I popped the polys with Luxman and Adcom 200w amps, but never have with either TFMs. I also never play them that loud anymore either.

    Hey Troy! Besides the esoteric amps or tube amplifiers that Carver made, this one [along with it's brother's] and the M-500t are tied as my favorite for sound. The TFM leans a bit more to the sound of a tube amp to me.

    Congrat's on your purchase, AC381.
    In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

    The best way to enjoy digital music reproduction is to never listen to good analogue reproduction.

    FYI: per Rolland....TFM- 35 models and below are not Magnetic field amps. Only the 42,45,55,75 are "maggies" in the TFM lineup.

    I have a Carver TFM-45. How do you turn up the gain on the amp?

    Again, even at full gain the amp does not put out 500 watts when you turn it on. If your blowing fuses it's because of your listening habits and sticky fingers on the volume dial.

    you don't unless you get inside. the TFM35x has pots on the back to adjust gain.

    The TFM-35 has a sort of volume knob. That is what I was referring to when I mentioned turning up the gain. Sorry if that was confusing!

    Its the THX dial on it, my AV-705x has them for each channel as well. The purpose of it was to be able to manually match the SPL between channels if your AVR wasnt capable of adding or subtracting gain itself.

    It's blowing fuses because you are overdriving the amp, which in turn is sending a clipped signal to the speakers.

    The claim that they sound like a tube amp is BS. If one has ever listened to a tube amp it's quite apparent. It may be of interest to know what is done in an effort to emulate the tube sound. A 1.5 ohm resistor is added just before the outputs. That's it.

    Thanks for clearing that up. The 45 in e house right now sounds a hell of a lot less like tubes than the marantz 2216. That comment had me a bit perplexed. The carver definitely doesn't sound bad, but tube-like is not one of the descriptors I'd use.
