re capping


I hear the phrase 'recapping'. when do you know when you should 're cap' an amplifier? I have a McIntosh mc602 amp that sounds fine to me. I also have a McIntosh mx132 that works ok for me. I also have a bose 901 series 2 active equalizer that seems to work ok. the 'red' on light kinda flashes now and then. if my system sounds ok, should I worry about my units?

Gotcha! I'm all too familiar with the vintage nuts who obsess over the superior sonic character of old, dried out, leaking caps. I like to tell them if they like those so much, I've got hundreds of old nasty caps to sell them.
