I just picked up a Zenith Solid State stereophonic portable turntable. When I turn it on it makes a humming sound. How can I fix it? The model number is NPS40. Thanks, Karen


This is a common problem for older audio equipment. It is caused by old capacitors drying out / changing values / shorting internally.

This problem can be minimized and even eliminated by a process called "forming". Forming is done by gradually applying the voltage to the device over time. You would need a piece of special equipment called an variable isolation to do this. You start at 0 volts and over the course of a day (or more) - gradually increase to 120 volts. Simply plugging the device into a 120 volt outlet defeats the forming process and once done - is irreversible - if the capacitors were the cause of the problem. The only thing left to do is to replace the capacitors; which restores the sound - but not the value of this vintage piece with new components (if that was your goal). Some technicians will install new capacitors inside the old ones to make it appear as original. You'll probably need to have this checked out by a pro.

Good luck!

No sound coming from turntable


Things to check:
1. is cart connected to arm, or are wires loose?
2. Is turntable connected to rest of system, or are wires loose?
3. Did this ever work, or is this a new connection? If new:

A. Does rest of system actually have a 'phono" input? If not, you may need a "pre-amp" to boost phono signal.

One of my DJ turntables = only left side stereo sound


need to narrow it down, using 1 turn table ONLY with the mixer on channel 1 (the chanel that is working) to test reciever is working properly and sound working on both side of the speakers, this eliminate the first turn table. Next, disconnect the working turn table (1) and connect your second turn table to the same chanel and see if you getting the sound coming chanel 1 just as your first turn table did. If you getting sound coming out from turn table on ch1 than is not the turn table issue. It will be you mixer having problems. You cant solve the problems having everything connected. Testing one turn table at a time using working chanel on the mixer to see if both turn table working properly. If you use the same chanel testing both turn table and the second one does not work than it will be one of your turn table is faulty. Note: if you find and test both of your turn table is working properly than it will be your mixer. good luck and hope that help..

Technics 1200MKII tonearm problem


Most of your question was missing, so I'm guessing what you were going to say.

It sounds as though one of the arm pivots - one vertical and one horizontal- has worked loose or broken. They are very delicate precision parts.

Unless you are very skilled you should leave this job to a specialist turntable dealer to fix.
