[sdiy] Preferred caps for polysynth recap ?

[Gil W.]

My synth. 

Wouldn't recap for the risk of failure ? It'll be ok.

 A couple
 relevant questions:
 Is this
 your own synth, or one you're working on for someone
 else?
 Do you have any
 indications that the electros are failing? 
 
 I agree with Gordon that a
 blanket replacement of parts has a high risk associated with
 it.  If we were talking tantalum caps, I'd lean more
 toward replacing them at this age, but if it's your own
 synth?  I wouldn't replace much else that wasn't
 failing already.

 not sure why you're saying that. Considering those caps
 are about 35 years old, I think it's quite important to
 refresh with new ones.
 
 
 
 I "works" and will work also after a recap.

  If it's working, I'd
 
  leave it alone.  Capacitors just don't fail as much
 as
 
  people think they do.  If you fanny about with the
 insides,
 
  you have a greater risk of damaging something than
 improving
 
  it.

  Won't make the tiniest bit of
 
  difference.
