Hi Rob,

I personally would stick with the same type of capacitor: if aluminum electrolytic, then use that; if tantalum, use that, etc. It may not matter much when a capacitor is used for a basic decoupling purpose but may matter if in a more critical circuit where the ESR becomes important.

Also, there is no need to ask permission since you own the equipment and bear the consequences of any ill-advised action...

Good luck,

I have in one mainframe so far (and planned on continuing) replaced the 1uf and lower electrolytic capacitors with Xicon Multilayer Ceramic Capacitors (MLCC) or Xicon Polyester Film Capacitors of the same capacitance. The voltage rating is 250V and the tolerances, etc. were better than the electrolytic I replaced. I didn't see the cost difference being very significant and thought they would last better than electrolytic. The scope responded favorably and is running fine. I did however save the ones I replaced and could go back if so recommended. Perhaps I should have asked first. However those that know me would say it is not out of character for me to beg forgiveness vs. ask for permission. In fact they would be surprised I even though enough to stop and start asking questions like this.
