We found the capacitor you are referring about it was right near the l-5021 transistor and I put a 22mf at 160 volts cap in place of the cap which said 40-3 whatever that means 40 mf at 3 volts? and the volume was still distorted but louder and when you turn it down slightly it decreases the volume fast very distorted.
