I recently bought a NAD 304 Stero Amp. I've plugged my turntable into it, but only get proper sound through the right hand channel. No matter how much i turn it up, the left channel stays the same volume. Even with all the balance shifted to the left it doesn't change volume. Any ideas?

Re: Sound through one channel
Only the right channel had a sound,the left channel is mute, whatever adjustment you did and whatever balancing you done nothigs happen,even you interchange the speakers. The problem is in the power amp. The STK IC there is busted already, it's better to change it with a new one so the performance become normal again.

well..this is one for the books. Can you tell me what the ratings are between the 252 and the 752 impedance matching wise? even though it might work sometimes, impedance matching can wreak havoc between mismatched amps.
Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.
Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???
first of all you can check either amp or pre is defect. for this change wiring left to right and right to left (pre to amp wiring). if still left channel has no sound the problemmaker is the amp. would be helpfull for further assistance if i know the model number.
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.
Because your amp has 4 channels on it on side A you can connect 2 speakers for left and right and the B you can do the same. your red is positive and black is negative. so in total you can have 4 speakers connected to your amp
