Hello, Buzz: I have never measured the temperature of my tubes, but I will say that output tubes like your 50L6 and rectifier tubes both tend to run very hot, as in hot enough to burn you if you touch them.
If the set exhibits no other problems besides trying to shock you (like all AC/DC sets try to do to me), I would not worry about it!
