RCA Victor VJT-29 solid state with left channel output problem

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. :(

    nvm, I fixed it. It was the resistor pack that biases the output transistor. Replaced it with a series of resistors in lieu of a new ceramic resistor pack

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: 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.

SOURCE: Amp won't power up,anymore! Even with new parts installed,removed

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
http://www.4qdtec.com/mostest.html

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

How can I check the Stanton 500 mk11 cartridge is good, I have no output in one channel ?


To really be sure, under a microscope to look at the diamiond, but i haven\'t seen one channel oke and one chanel no sound. Then it should allways makes sound , only ckrackling. So be sure your wires are fit by tightening the connection and measure your output till the last connection with your stylus and move your connections a bit , if that\'s allright , then is it a cable or input from something outside your tt. But have you checked it also with first cleaning your needle well and another record and lift each side of the turntable a bit. Sometimes is one dust particle enough, even with a new stylus. Is your output line or phono? O a technics, take the whole needle out and those fours pins you have to lubricate with right stuf ( a tiny bit ) and move them in and out and you havent cheked the connection with your om/concorde, but i think that one pin won\'t come out totally, so pull a bit ( after lubrication ) push them all inside and watch if they come all four back. And pls replace those terrible quality rca cables from technics, they are crap and a nice pair from another brand is only 30 euro a pair, but you needle ain\'t broke for sure and does it work with another unit?.......(still clean and lubricate the stuff).I hear from you.

I have a Technics turntable Model: SL-BD22-KM, Ser.#: GF3Fc73813. The RCA and ground connection panel on the turntable has been jurked-out tearing the wires apart. I need to know which wires are soldered...


hi,
Here is the wiring of the turntable RCA plug ( RCA wire will have 4 connections like red and its outer wire then White and its outer wire.). connect these as follows.

For right channel

Red wire from the turntable to the red center wire of the RCA plug

Green wire from the turntable to the outer wire with red wire of the RCA plug

For left channel

White wire from the turntable to the white center wire of the RCA plug

Blue wire from the turntable to the outer wire with White wire of the RCA plug
OK

I have vestax 05pro2. Left channel works but out of one speaker. The turntable input is good. Im thinking Its either the channel fader, or the rca inputs for that side. Has anyone had this problem?


Hi,
Here's a solution to see if you have a problem with either your receiver or turntable.
The turntable has 2 RCA's one red for right channel, and one white or black for left channel, which plug into the back of the amplifier.

  • Unplug both RCA from rear of amplifier.
  • Plug in a cd or dvd player into those inputs on the amplifier, the sound will be lower but it will give you an indication if the amplifier is ok or not.
  • If you have sound on both channels left and right then the amplifier is good
  • If you still only have sound on left channel, then there is a problem with the right channel input on the amp.
  • If your amp, is good, unplug the cd /dvd player.
  • Put a record on and start playing the record
  • Plug the white or black RCA from the turntable into the rear of the amplifier marked left, you should have sound.
  • now unplug it from the left and plug in into the right red RCA socket, if you have sound the amplifier is working fine.
  • if there is no sound there may be a problem with the stylus cartridge on the turntable
  • now lets reverse the test
  • unplug both RCA from amp.
  • Plug the red RCA into the left socket on amplifier, if there is sound, turntable is working fine, if no sound there is a problem with either the stylus cartridge or that red RCA cable.
  • now unplug the red RCA from the left side and plug it into the right side socket
  • if there is no sound there may be a problem with the stylus cartridge or RCA cable.
I hope this helps

Technics 1310 turntable has left channel (white


There are just two causes, one is the preamp, which can be easily checked by putting the right channel jack in the left terminal. If the sound is normal, then it's likely that the cartridge in the deck is bad, or some wire is loose. However if the sound is still poor then the magnetic cartridge preamp in the amp has a fault. These are normally a single IC, which will have failed. Find the preamp by tracing the wires from the imput socket to the PC board, which may be alone.

Sony PS-LX300USB Turntable, one channel not working


Have you tried swopping over the output leads from the turntable to the amp (normally one red and one white phono plug) so they are in each others socket? If you do this and you still get no sound from the right channel it is almost certain to be a faulty amp,or speaker.
If you swop and get no sound from the LEFT channel it is could be either a faulty lead or cartridge.
