I am the recent recipeint of an early pair of GNP 2-way bookshelf speakers (a friend of mine was a classmate of Richard Gross), and while the surrounds are gone- I can fix that - I also notices that there was a 4.7uF/50V electrolytic cap in the crossover and I am wondering if it should be replaced?
and if so with what?
any suggestions?
Happy Listening
Follow Ups:
Be aware that replacing a lossy electrolytic capacitor with a low-loss film capacitor tends to increase the perceived output level, so you may find it necessary to attenuate the output of the tweeter with an L-pad, or increase the attenuation level if a stock L-pad is already involved. However, you might find an increase of treble energy to be a good thing. Also, premium film capacitors tend to be rather large, so make sure to choose one that is small enough to fit onto the crossover circuit board, or small enough to place within a point-to-point wiring scheme. While you are at it, you might consider upgrading the internal wiring, or simply choose new hookup wire for the task.
Duster,
I am aware that changing the cap may well alter the original balance - but - in that the surround came of very easily - I am very confidant that the cap is past its prime-
How about the Duelund 16 ga silver tinned wire for hook-up?

I can't comment on the Duelund hookup wire, since I have no experience of it. If you are ready to replace the stock electrolytic cap, and you have room for it (it's a very large cap), I suggest the Jantzen Audio 4.7uF 800V Z-Superior capacitor, since it is a neutral-sounding cap, with excellent detail retrieval, with no glare nor brightness. A safe-bet for an electrolytic cap to premium cap upgrade, IMO.

Duster-
Thank You-
I'll give it a try!
Happy Listening
