This set will put a smile on your children for a long time to come! This set is not to be confused with the earlier battery powered  set which required numerous battery replacements.This is the up graded version which is run by a 12-15 volt transformer!I have just serviced & cleaned the set including the pickup braides and tested it which works perfectly!The set is complete as per contents on the side of the box.The box has protected the set from damage but the box corners are showing wear.How many children will play with the box?
