Fido Posted December 29, 2022 Share Posted December 29, 2022 I gave my old Cerwin Vega 380 SEs to my nephew a few years ago. To me the crossovers sound out of spec. Here is a picture of one of the Crossovers out of one of the speakers. Can anyone help me identify the capacitor types and values in this picture so we can replace them to bring them back to spec? Thanks in advance for any help any of you can provide? 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted December 29, 2022 Share Posted December 29, 2022 The silver one I can read is a 40 microfarad non-polarized electrolytic. It says 110 volt but that is overkill for a speaker, you could get by with a lesser voltage rated one but keep the 40 microfarads the same. I can't make out the silver one on the right from your shot but it looks like an electrolytic as well. I would just replace those two first and see if it sounds better. Electrolytics are the ones that dry out and go out of spec. The other yellow ones are mylar or film caps and are PROBABLY OK. 3 Quote Link to comment Share on other sites More sharing options...

KT88 Posted January 3, 2023 Share Posted January 3, 2023 Agree with all posts. What is this little black box above the yellow 5 uF Mylar cap? Quote Link to comment Share on other sites More sharing options...

babadono Posted January 4, 2023 Share Posted January 4, 2023 It is not that complicated...just reverse engineer. You do know which wires are the input. And which output wires go to which driver(s)? Or is it completely disconnected and you don't know what wires goes where? Quote Link to comment Share on other sites More sharing options...
