I hooked up my ancient Philips TT to a Sansui integrated over the weekend, and was greeted by a loud hum, and no musical output. The phono input is working (I tested it with a line level input at low volumes) as is the TT (tested it with my guitar amp). Is it a grounding issue? Both the amp and TT have 2 pin plugs; however, the amp has a plug at the back with reads GND. Do I take a cable and plug it into the ground of the socket the amp is plugged into? Am I on the right track, or am I missing something? People on the board who have a working knowledge of electrical engineering, please do help. I don't want to plug all this in, only to find that the amp is blown forever! Thanks. |

Your tone arm cable should have grounding wire which has to be connected to the ground of your amp. If this grounding wire is missing check if it's possibly cut off and fix a new one. |

You are correct. You will have connect the Ground of the turntable to the ground of the phono-stage...or the GND pin of the amp (if the phono-stage is built into the amp) It's okay if your amp and TT has only 2 pin...its not ideal, but okay. |

Thanks a ton  Will try this over the weekend. Will ask you guys again if I can't locate the ground wire on the TT! Just a question...why isn't the hum there on the other amp I used (a Laney guitar amp)? Is it because of the 3 pin plug or is there any other reason? |
