Tantalums of that era are not as reliable as their modern equilvalents. When a tanalum fails it usually shorts. Modern tantalums have built in fuses to limit the fireworks should a failure occur. High quality test equipment from the TR-7 era or earlier often have issues with tantalums and I know of people that will routinely replace all of them once they are into the instrument. Owners of KWM-380's will do the same thing.
