Experience on replacing capacitors of SS preamp?


I have done replacing blown resistors from a tube amp before, but not capacitors.
Replacing capacitors would be as easy as replacing resistors?
I will have an old SS AR preamp which is over 20 years old, and am thinking about replacing all caps by myself, but I'd like to hear any caution or tips of doing the job.

thx

It’s still just soldering. Protect the component from excess heat(I use mini alligator clips(heat sinks), on the leads closest to the part). Using solders with low melting points(ie: eutectics, Cardas, Wonder, etc) makes things easier too. With some components(ie: some electrolytic caps) , it’s critical to observe/annotate their polarity, where applicable. (https://learn.sparkfun.com/tutorials/polarity/alI) If soldering point to point, made a good mechanical connection first. If your intent is to replace the capacitors, that have suffered from age: just do the electrolytics. Most other types(ie: film, tantalum, ceramics), don’t dry out or leak. Upgrading(POOGE) is another story. Have fun! https://www.powells.com/book/audio-electronics-the-pooge-chronicles-9781882580149
