Marantz 2500 Volume Control -- Help!


MY MARANTZ 2500'S VOLUME CONTROL OCCASIONALLY GETS QUIET ON THE LEFT CHANNEL ONLY . ROTATING IT A FEW TIMES RESTORES THE SOUND . WILL A SPRAY , CLEAN AND LUBE , CLEAR UP THE PROBLEM OR IS THIS A SIGN THAT THE VOLUME CONTROL WILL NEED TO BE REPLACED FROM AN OXIDIZED WINDING ?I APPRECIATE THIS SITE AND THE VAST KNOWLEDGE OF IT'S MEMBERS . THANK YOU .

Thank you Zawwin , How long will this take care of this situation ? Months , Years ? FBI .
If the job is done right it should last 3-5 yrs. You will need to activate all the switches and buttons 5-10 times every month or so to burnish off the oxidation. If you follow this procedure
ZAWWIN , Upon rereading your original letter I decided tdo the obvious , ya know , the things I learned about 25 years o ago in high school and college . Jack LaLane is right " Use it or lose it !!" The intermittent loss was caused by the seldom used filter switch for frequency rolloff , namely the 9KHz . On my 1969 Fisher I Worked all switches and buttons before a listening session to get the cleanest sound I could . Well , a wife and children later I must be getting a little less fanatic about my music . Time to rekindle the audio fire , it's not too late . Once again thank you , you are a ZAWINNER . May GOD richly bless you .
