I want to do an entire analog board recap for my Mac Classic II. For the PSU part (there is a big group of caps, and you can see a green stain around the board where they are) I would be using low-ESR. For the rest, which should be the CRT circuitry, I would be using high frequency.

The problem is, I don't know what would happen if I put in regular capacitors in the CRT circuitry. Would it work fine? Would it fail quickly? Would it just not last as long? What would happen?

So, what if I replaced them all with high frequency, or if I replaced them all with low-ESR?

Sure it may not be necessary to recap an entire A/B, but I just want to be safe!
