Many Tantalum caps do not have a voltage designator band. This one is supposed to be 50V, according to the parts list. That Voltage Value can usually be derived indirectly from the known operating voltage of the circuit. In this case, common sense tells us this cannot be a 16V cap, since it is operating in a circuit using a higher voltage than 16V. You would want to replace this with one of at least the same or greater voltage rating.
If you're going to the trouble of ordering new ones and replacing, I
believe it's also now understood to be good practice to de-rate
tantalums by *at least* 2 x the operating voltage.
(In these lists I've heard a lot of cases where the originals were
barely de-rated and thereby producing unnecessary failures -- even in
Tek gear, perhaps moreso the newer SMT.)
