Transmaster Posted June 23, 2018 Report Share Posted June 23, 2018 A number of years ago I rebuilt the crossovers on a pair of Wharfdale W35 speakers. Then I used Dayton flim cap’s. In the meantime one of these W35’s got Dc’ed by a failing Onkyo Amp. It took me 5 years to collect the parts to fix it. I landed a pair of crossovers that had the originsl circa 1970 Minerva NPE’s from Hong Kong. I tested them on my capacitor tester and except for being out of spec μF wise they were not in bad shape. Their ESR’s, and Vloss were OK. Knowing vastly more about this sort of thing I replaced them with Mundorf E-Cap plain NPE’s. Everything I liked about the sound of these W35’s is there and so much better. These caps burnt in in just a few hours. The total cost of these German made Mundorf E-Cap’s was $23 Dollars. It was so nice not having to figure out how to fit capacitors that were the size of a Red Bull pop can. I had to parallel the capacitor on the Woofer side I needed a 12 μF the E-cap had a 10μf, than jumped to 15μF. So I paralleled a 1.5μF E-Cap which resulted in a total value of 12.78μF close enough. These Mundorf E-Caps are the best quality electrolyics I have ever seen. Here is one of the rebuilt crossovers with the Mundorf E-Cap’s plains. Yellow common negative, Red Woofer, Blue tweeter, Black Midrange. Quote Link to comment Share on other sites More sharing options...
