Replacing a Faulty Turntable Motor or Power Supply

Faulty turntable motor

If your turntable motor or power supply develops a fault then the following suggestions are made:

  1. Contact the turntable’s manufacturer of your deck, if possible.
  2. If you cannot contact the manufacturer then before you start searching for a new motor online, the following factors should be considered.
  • Most turntables use AC motors which turn at a fixed speed. Any replacement motor must turn at exactly the same speed as the original.
  • A good number of older motors are no longer being manufactured
  • Even if you find a compatible motor that has the correct speed, size and shaft diameter, you will then need to fit the pulley from your old motor. Sometimes the pulley is removable which makes this step easy. However, they are often press fitted, in which case removal is much more difficult, not to mention re-fitting to any new motor. The motor can easily be ruined if you are not careful.
  • To get around the problem above, some people try to acquire a replacement pulley. The problem with replacing a pulley is that it needs to be precisely the right diameter if the turntable is to run at the same speed. Also, the inner hole must be very precise and concentric if it is to fit your motor shaft without wobble. To get a pulley manufactured correctly by a local machinist is surprisingly expensive and a lot can be misunderstood or go wrong. We do not even quote for this type of work.

Faulty Turntable Power Supply

If your power supply has developed a fault then hopefully it can be fixed by the manufacturer. However this can prove even more costly than the price of our dc motor kit. If this is the case then it’s a good idea to question why you would want to have a mere repair rather than a massive upgrade.

Conclusion

For fixing older budget decks it’s easy to baulk at the cost of something like a dc motor kit (starting at £250). In some cases the best answer is to simply part with a faulty deck and aquire a new one. The argument against this is that some older decks are still good performers against many of the mediocre modern turntables. The vast majority of designs have not advanced much ( if at all ) over the years. Many decks are built to a price without much emphasis on performance. It’s difficult to know sometimes how older decks stack up against newer rivals and forums are one way to gain access to wider experience.

What you can be sure of is that you can also upgrade the performance of an older deck enormously by installing an Origin Live dc motor kit. This alone can enable older decks to outperform modern equivalents. There are also other inexpensive upgrades like the Origin Live platter mat, upgrade belt and platter glide oil which all contribute to transforming performance not to mention our tonearms.

It’s an interesting mix of factors and your decision will depend much on budget and end aspiration. If you feel it’s time to part company with an older deck and wish for an upgrade that no amount of modification will ever come close to, then the Origin Live turntables are absolutely outstanding.
