Tom,
C861 is the one that will give trouble, 13V on a 15V tantalum. I keep 47mfd 25V ULD types in stock to replace the tantalums that are bad. Higher capacitance for others such as 100mfd can be higher in value if wanted. The decoupling off the 50V supply, I put in 15mfd in place of the ,68mfd. The original tantalum, ,68mfd, was already high in ESR. I prefer to use a 25V electrolytic to replace a 20V tantalum on a 15V supply.
