Replacing Tantalum Capacitors

My Emulator 1 was behaving a bit odd today, so I opened it up, and a few of the tant caps on the digital board have a rather low resistance reading (That is in circuit, however) coming in at about 1k ohms..

When I first got it, about 2 were short circuit and smoking.. when I replaced them it was all fine etc..

So, I'm going to pre-empt the others failing, and replace them all, (about 15) with new ones..

My question is, should I use tantalums, or are electrolytics fine for this purpose?

Regards
Mike

I would stick with new tantalums, they can often be replaced with electro's, but in some applications you would need low leakage electrolytics. For a small number like that just use the same components, it will save you having to second guess the design engineer.
