Yes, do have tubes tested, but on vintage sets that have not been used in decades tubes are the least of your problems. At very least the electrolytic capacitors in the power supply section are almost certainly bad, and should be replaced BEFORE you attempt to fire the set up with mains power. Once you get a schematic, post a copy of it here and someone will help you identify these "must dos."
