Carver C11 preamp problem

I have a Carver Preamp that is about 20 years old. It works fine except when left on for an extended period of time it makes a popping sound through the output stage.

I found out through the Carver Audio forums that metal shavings inside the case are an issue with this unit. So I used an achohol based spray and cleaned the switchs and the circuit board, (there was a fair amount of shavings found). It has been running for 14 hours with no problems.

Carver TFM 35 amp what is the best way to hook it to a Marantz AV8003 pre app


No. You should use the line(or preamp output) to the Carver input. The only way you could use the tape output is if the Carver has input volume controls.

Please see my last few comments on the same issue. If you can't find it, please let me know. BTW, Marantz does not show the AZ8003 to be a valid model.

Yamaha m70 amp and c70 pre-amp right speaker stopped working


First, lets's determine if it's the amp or the preamp...

Swap the Left and Right channel cables between preamp and the amp with each other.

Did it stay on the right? = amp problem.

Now on the left? Preamp or source.

Plug any Line Level device (CD?) directly into the amp inputs. Work now? Preamp problem.

ALL sources? Preamp - toggle all controls, especially a Tape Monitor to possibly wipe of any built-up oxides in them.

My turntable connect to Carver Preamp, I bought a


If you can hear music with the volume up, but like it was turned down low (from the power amp), then yes there is something up with it. If it's the same on both left & right channels, then it's something common to both. For instance the power supply, or an IC that has both channels going in it.
If however the power amp does produce sound normally with another device, then either the turntable has a fault, or the pre-amp has, perhaps on the pre-amp inside it for the cartridge.

Carver CT-28v Tuner preamp - Has a hum/buzz (soundls like a ground loop) that is heard as soon as the unit is turned on. Does not increase with volume, just stays the same and is continuous. Changing...


Reverse the polarity of the AC plug and try it. Is there a headphone jack on the preamp? Try headphones with the preamp standalone without the amp attached.

Are you sure the preamp is the problem? I assume you also have an amp or you wouldn't hear anything. Power up the amp with nothing but speakers attached. Hum??? It's in the amp. No Hum? Attach just the preamp with no external components. Hum now? It's the CT-28. Turn it off an exercise every switch and knob throughout its range numerous times. Try again. Still humming? Manipulate source selections, Tape Monitor, everything.
