MP3 and digital media players!

Two thoughts here.

On a machine of this age, there's a good chance that any electrolytic capacitors are well past their best. It may be worth replacing them all (it's not hard to identify suitable replacements and they're very inexpensive) before one of them goes bang - it being much easier to identify a suitable replacement by reading an intact can than by trying to piece together lumps of shrapnel you've just sponged out the works.

The history of problems coming on half way through a record hints at a component overheating problem. Have a careful look around for components showing signs of distress. At the same time, examine all the soldered connections you can find, as dry joints can sometimes behave differently when warm (look for soldered joints which aren't as shiny as their neighbours, don't very evidently "wet" both the surfaces they're meant to join, or look all balled up rather than the nice concave shape you expect to see)

Good luck.

A.

Output distortion from bass amp


The amp is clipping the signal. This could be from the input being too high. The impedance being too low or the finals are damaged.

Could be, but check the wiring to the cartridge, plus the connection to your amp. A poor earth wire or one touching the other can make it sound tinny.

All is fine with this turntable eccept for the fact that when the sound comes through the speakers you can make out the track but the sound is distorted.


Hello
You don't say whether you have only just acquired this deck or if you have been using it for some time and it has only now started to give problems.
There are 2 or 3 possible explanations.
  1. If you have only just got this deck and are using it on a stereo that has a dedicated phono (record player) input it may be that you need to get inside your turntable to turn off the built in pre-amplifier switch. To do so make sure the tone arm is securely fixed into it's holder (a rubber band will hold it in tightly) before turning the deck upside down and unscrewing the bottom.
  2. If you have just got this deck and are trying to play it through a stereo system that does NOT have a dedicated phono (record player) input you may need to get inside the deck to turn the phono pre-amplifier switch on.
  3. And if the deck has been used for some time this is the most likely - the record stylus (needle) probably needs replacing. Personally, although it is a bit more expensive, I prefer to replace the whole cartridge rather than just the stylus as they do need changing from time to time anyway. Always replace the stylus at least at the frequency recommended by the manufacturer. Regularly clean the stylus with very gentle strokes from the back towards the front using a small soft brush.

I bought an Audio Technica USB AT LP 120 Turntable last June. It worked fine as a turntable, but I was never able to get good recordings of vinyl without distortion. But now I have another problem: when...


Sorry it could be the cartridge! They can fail at anytime, only the stylus will wear with time. However it could be the amplifer's magnetic cartridge pre-amp. If you look inside your amp and trace back from the phono socket you should find the pre-amp. If it is distorting on both channels it's probably an IC that has failed.

Playback distortion


Good day sir, distortion can be caused by several factors, 1. overdriven audio source, try tuning down the volume to half. 2. the speakers are defective due to driver's coil scratching the magnet. need to replace the speakers, better swap first any good known speakers. hope this may help. if you may have any more questions, feel free to ask again. thanks

Record player sounds scratchy and tinny


Playing records is a contact sport.

Since the needle touches the record -- as opposed to a laser reading a CD -- any bit of dust or mold translates to annoying pops and hisses.

Record cleaners get down into the record grooves to extract dust and particles.

Or you may need a new needle.

Distortion caused by stylus?


Cannot say without seeing it but if you wish to play a 78 then it needs a different size stylus to a 45 or LP. Make sure the correct stylus is fitted.

On 1950s-60s twin valve amps in record players two questions how do you stop the loudish hum and how do you increase the volume. Thanks.


The hum is because of bad capacitors in the power supply area. Many of these have caps in the large silver cans. Replace them using standard electrolytic caps and the hum should go away. Once that is gone, the volume should return as well.
