I have a lot of 80's/90s electronic musical equipment (synthesizers etc.) and a couple of vintage computers from that same era which I want to recap as a preventive measure even though they mostly work fine for the time being.
Finding quality branded caps (Nichicon, Panasonic, Rubycon etc.) with a long life rating (i.e. 10 000 hours) and high temperature rating (105C) along with the same uF values and equal or higher voltage ratings is also a no-brainer, but apart from that -which type?
General purpose types, low-ESR, ultra-low ESR..?
In a separate discussion here, concerning an old (early 90s as far as I know) switched mode power supply for an Atari ST computer I've learnt that it might not be as simple as "just replace all the electrolytics with quality branded low-ESR types", but really, "it depends...".
So, for a DIY electronics hobbyist like myself, what would you suggest I use when recapping (i'm talking about electrolytics below as I understand I usually don't need to concerned about the other ones) for instance:
a) caps on 80's/90's computer motherboards (i.e. my Atari ST)
b) caps inside 80's/90's music synthesizers, drum machines, mixers and other audio related gear
c) caps on power supplies (not switched mode ones, but the big transformer types with rectifier/filtering boards)
d) caps in switched mode power supplies (I've discussed this separately already, and it appears to be a complex issues, but I'm still open for learning more on the subject).
