TURNTABLE SETUP Questions thread - don't start a new thread, ASK YOUR QUESTION HERE! - Page 237

post #3541 of 3547

Thanks!

 

The problem I'm facing is that only one channel has any output.

I'm not really sure how to systematically troubleshoot this -  so far I've only tried rearranging the connections between the tonearm and the phono cartridge.

 

Any insight you have would be highly appreciated!

I think it's important to know exactly how to connect the tonearm to the cartridge, and not just rearrange them. Have you verified exactly where each one goes?

There are a few other possibilities. It could also be the amp, or one bad side of an RCA cable is loose, or damaged inside.

Try and flip the L and R from the turntable into the phono or amp. Does the dead channel switch?

We can work out the possibilities from there.

The cartridge I received doesn't explicitly specify where each of the ground wires goes, so I connected the left and right channel connections to the appropriate positions and then tried the two possible combinations of ground connections. Neither of these resulted in any change in output. I also tried tightening the sleeves around which the wires are enveloped (in case the connections were loose), but this had no effect.

I tried this and the dead channel did switch!

 

Would this decrease the probability that it's a problem with the amp?

 

I also wouldn't say the channel is absolutely dead - there seems to be noise coming out of the channel, it just doesn't seem to be amplifying the audio signal from the vinyl.

Do you have a multimeter that could give a continuity reading? Try disconnecting the cartridge from the leads or just test on the RCA terminals. An open circuit means a dead channel.

Some cartridges are color coded, some are not (like the Grado).  Generally, red is right +, white is left +, green is right - and blue is left -.

 

If the issue changed channels when you changed the connections, the problem is not the preamp.  You might have a bad tonearm lead (from the tonearm to the cartridge or from the tonearm to the preamp.  It could also be as simple as ensuring the cables are plugged all the way in.

The four wires that connect the tonearm to the phono cartridge are color coded. Do the wires match the color coding on the cartridge pins? Are they all securely connected and do the wires all look intact?
