I don't normally go in for wholesale capacitor replacement, but I have just replaced all the tantalum capacitors in an EAI1000 analogue computer with modern aluminium electrolytics. I had a couple of the tants short, one killed the -15V supply (not enough current from said rail to cause the tant to explode) which did little damage. The other shorted the +8V to -8V rail, causing at least one IC to die with it. I did not what a repeat performance so I changed the lot.
