Question about RCA Audio Players & Recorders
Recent craigslist acquisition.... Turntable and Radio work fine, just need a bit of cleaning of the knobs,pots, etc. My right channel sounds great, however my left channel has an overiding crackling, fuzz noise. I'm confident its not a 60hz power supply noise or I would be hearing it out of both channels right? I still hear some faint audio from it, just the fuzz overtop is overwhelming such that I unhooked the speaker channel. I swapped speaker sides to the different outputs and the problem follows the amp output. It seems the output for the left is bad. Potentially cap or output transistor maybe? Anyone have any ideas? Until then, I am listening to just the left channel. :(

SOURCE: very low audio output
Make sure your receiver has a PHONO input. If you are connecting it to a LINE or AUX input, then there is not enough signal to boost the sound coming from the turntable. Turntables require a PHONO input, because phono input's have a pre-amp on them, which boost the turntable signal. If you do not have a PHONO input on your receiver, you will need to buy a Phono Pre-Amp.
If you have a phono input, then you might have an issue with the turntable's RCA cables, or your cartridge may be at fault.

SOURCE: No Sound out of Left side
is it possible to swap the left and right wires on the needle cartridge? does the sound change sides? if yes bad cartridge if you still only get sound from right side try changing around the rca phono plugs

SOURCE: sound problem
You might also have a bad tonearm connection - make sure your headshell is securely in place. Also take a look at the tonearm pins, this is the 4 pins inside the tonearm, where your headshell connects. If any of the pins are pushed in, then you have a faulty tonearm.
The most common issue with sound is the RCA cables, so I would suggest replacing those first before you go to the tonearm, as the tonearms are pretty expensive.

turntable needs high sensitivity preamp. the output level is so low that it has to be amplified more. usual inputs of turntable are phono input. needs a high sensitive input to handle.hope this help.

Hiya, dont have a diag either what you will have to try and is compare the left channel with the right. There will be 2 driver transistors (also likely on heatsink) close to the outputs. Check which driver drives which output on the left, then match it on the right. Those same drivers could very well also be a problem on the right as they often go with the outputs. There is a possibilty they have smoked again. See here to test FETS
Basically the left will match the right but not similar locations but definitely by track joins.
Also check the power resistors at the output. Often also go.
Hope that helps
