Quick Panasonic Radio Casette Player Fix - Volume Control Faulty

A friend had a Panasonic Radio Casette player that had an issue with the volume control going loud at the low end instead of quiet, I agreed to have a look at it as I thought it would make an interesting though hopefully simple repair and I was right Simple crudded up tracks on the volume slider was ultimatly the only issue, a quick clean and right as rain I recorded the fix anyway and here it is. One of my shortest videos to date ?? it may prove interesting to some of you so enjoy Peter
