The capacitor may play a roll. However tolerances on electrolytic caps were usually very wide, sometimes -20%/+80%, so they were seldom used if the value was critical. Modern electrolytics can have somewhat tighter tolerances, but still not great.
Of course the tube is also a possibility, as well as resistors.
It does sound like the pot is bad.
