The sub is good. I've newer seen a 6H6 glass tube, but either one will work. You may have to spray a little deoxit or WD40 from underneath the chassis on the socket, and gently pry this tube out with 2 screwdrivers at the same time on opposite sides. Eventually you will get it out. But then again, these seldom fail, so after the recapping, etc... you might be good to go.
