First off....you didn't say if you are a tech or not. I'll make this really simple.

If you are not a seasoned tech with experience solving carver problems....you will waste tons of time and money guessing what the problem might be.

Carvers are quite the unique beast. They deliver whopping amounts of power in a small chassis. This is done by using a trick switching power supply. There can be any number of possible problems.

To properly diagnose this you will need an oscilloscope, signal generator, variac, and of course a really good quality multimeter that can test diodes and transistors.

IF and only IF you are a seasoned tech with all the above equipment, that has no experience repairing carver, then go online to ebay, find member techman777, and for around $15 you can get a nicely reprinted service manual. Troubleshooting expertise and the manual will take you foreward from there because the manual has a very thorough troubleshooting guide in it.

If you think you can fudge your way through the guide without any serious electronics knowledge, you are in for a rude shock as you will find that you are an earth man trying to read martian.

If you are just a casual fix it guy ( nothing wrong with that !!! ), I strongly suggest that you do NOT make this your first try at fixing an amp.

The value of these, in mint condition, all rebuilt is around $350- $450 on ebay all day long. if you are willing to invest that much, you can look up carver audio repair on google and send it off to them, as they are reported to do a nice job. OR....you can look me up on ebay, send it to me and I will do a nice job too, and that comes from 20+ years of repairing.

I know that this isn't much help, but carvers are very special, and require special knowledge to repair.

Best of luck.....Rob

Is it normal for carver power amps to have a slight hum? I have a carver-55x


Hum can come from a jillion different places. Is this hum coming from the unit with no speakers connected, or is it heard through the speakers? What sources are being used? What cables? Are thereany common sources of interference near? Troubleshooting is difficult without much information.

Carver r2000 keeps blowing fuse


Fuses blow when there's an overload. The most likely cause being a short-circuited semiconductor(s) located on the big heatsink. Other causes are a shorted device in the power supply section. Such as a rectifier or voltage control device.

Transistors tested with an ohm meter will show up as if you have touched the leads together when connecting across the terminals.

It's not bridgeable according to the manual.

Who specs an amp at 3 ohms anyway? Your Carver might be just as effectively powerful.

Carver amp started making a low fluttering sound.


I have a Carver amp which developed a "hum" also. As a troubleshooting step only (long term this is NOT a solution) you can use a ground plug adapter that removes the ground lug from the unit. This is an adapter that has THREE (Line, Neutral, Ground) female sockets for the amp to be plugged into, and TWO male plugs to go into a wall socket. If the buzz goes away, you've got a leaky capacitor in the Power Supply section of the amp. It will take some doing to actually fix the problem, but this will narrow down the cause.

T12.5L 250V fuse for carver amp


Yes T1 stands for fuse One. The fuse is a 2.5amp at 250volts. The only thing you need to work out now is if it's a Quick blow or Slow Blow type. Sometimes you can still see the remains of the wire that's gone on the old one. This is your best clue to it. If it is a single wire it's a Quick, if you can see a coil then it's the other.
If in doubt use a Quick blow type.

I have a carver M 1.5 amp rt. channel is out.


Carver designs in general are not easy to repair. I would recommend that you send this unit into a Carver authorized service center. The likely problem is the output transistors, but the driver circuits and predrivers are not simple designs and if there is a problem there, it could effect the outputs. Tracing this will require equipment and schematics that I don't believe are available on the net.
