  • Yorkville E215 cabinet

    I have this huge extremely heavy cabinet here for repair....It has two 15's and a horn.....the horn was dead......due to the fact that this cabinet is used outdoors for festivals, it is subjected to moisture and dampness.....the horn itself had checked ok....so I suspected the crossover...after poking around for abit, I discovered that there was a capacitor labeled C6 which was soldered to the board but had a fractured lead between the body of the component and the solder joint on the other side..

    it was fractured where it passes through the board and the customer was complaining about the horn cracking...this capacitor was actually secured to the board with some RTV silicone...so it really couldn't move....I am no expert here by any means, but I would assume that the high freq overtones.....maybe the ones that you can't hear caused this section of lead to vibrate at a very fast rate and had eventually snapped the lead completely in two.....same as if you had cut it with a pair of cutters...every other component was fine....

    also.....there is a switch which is used to select bi-amp mode or full range mode....if it is switched to bi-amp mode, the horn is dis-connected so you have to make sure it is set right....and finally, you don't need a 2000W amp to check out the crossover for a dead horn or woofer...I used a portable cd player with a headphone out and ran that into the crossover and connected up a small 3 inch spkr to the horn connections...when I found the problem I was able to get sound in the speaker....once I change the speakon connectors (as they are corroded), I am going to coat all the jacks with a moisture resistant paste like one would find in the tail light lenses back in the day to prevent moisture from corroding connections in the future....after that, I will run the cab through a power amp just to make sure everything is fine....

    So are you just reporting this or do you need help with something? Low frequency vibrations at high volume will break component leads...no ultrasonic frequencies present normally. Maybe it was partially cut at assembly time and finally broke. I've seen weirder stuff from the factory.

    Bi-amp takes the crossover out and allows you to wire amps directly to horn and 15" drivers. You need to run an active crossover before the amplifiers with this setup. Pro rigs are bi and tri amped for better sound and efficiency.

    Any paste or grease you apply will just be a magnet for dirt and crud. There is no need to do this with new speakons. I have never heard of any pro PA company doing that to their cabinets, and they run them outdoors all the time.

      Actually no...I have it repaired..I just posted it in the event somebody else had a similar problem with one.....

      I was actually referring to the bi-amp switch so that if it is set in the wrong position and you were trying to troubleshoot a dead horn issue, it would never work.....

      big pro PA companies probably have technicians on staff......they would be crazy not to...after every show the equipment is checked out once it gets back to the site...every time....these guys will probably spot corrosion on jacks and will replace them when needed....before that next big paying gig... it should be on a preventive maintenance list anyway.....the person who owns this rig..(not a company), does outdoor venues all summer and here on the east coast it is extremely damp....so that is why they had asked about that...

      Thank you very much for the reply....I appreciate it very much....
      Cheers

          bsco I know this is an old post but I joined just to thank you so much for posting this information about the E215. You just saved me several hours of troubleshooting. I was losing my mind trying to figure out what was causing my speakers horns in both speakers to be intermittent. It was so frustrating I took the crossover board out and checked everything looked alright. Then you mentioned the c6 capacitor and I couldn't find it on the crossover board but I found it on the input board where the 1/4" male speaker wire plugs in. I verified the capacitor and read 10 microF then just wiggling the capacitor and I would lose the reading. I took a soldering iron and heated the solder and the broken lead of the capacitor came right out. Both my E215 speaker had the same problem. Thanks so much for the info. Anyone have the right part number to get replacement capacitors? I just soldered another lead on the broken end of the capacitor lead to temporarily get it working for now but would like to get the right part glued back in.

            It is a 10uF 100V polyester cap. Anything of that type and value will work.
            The actual yorkville part # is 5930
            Service manual is available here: http://yorkville.com/downloads/servman/sm_e215.pdf

              Thanks for the part number. I'm trying to find an online distributor for yorkville parts but can't find one? Does anyone know of one exists?

                  Thanks the dude , I've ordered from digikey before but because they are located in the states it cost more for shipping, the exchange 30% more and on top of that they don't ship USPS, only fedex, DHL and UPS and they all tack on a stupid brokerage fee which can be just as much as the capacitors are worth. For 4 capacitors its gonna cost me like $80 when its all said and done. Before going that route I'm going to try to find a supplier in Canada. Many thanks though for your suggestion.

                    Apologies. If you update your profile with your location, you'll get better help. I wasn't aware you were in Canada as no location is listed in your profile.

                        Well firstly, WELCOME TO THE PLACE!
                        We have some Canadian members here. Hopefully they'll chime in. I know nothing of where to get parts in Canada. I do see that Mouser has a Canadian website, but I'm not sure if you still have to pay cross-boarder shipping. Just in case, here's another link.

                          I get most of my parts from digikey.ca
                          They ship Fedex and do not charge a brokerage fee. Flat rate $8 shipping and you will have it the next day.
                          Here is the same part The Dude linked, but on the Canadian site:

                            I'll chime in.....I think they are like Digi Key...the Canadian price includes everything except shipping which is only $8...for me, where I am in Nfld it takes a couple extra days for me to get it...It takes g1 less time probably because he is not on an island and due to the fact thet he is probably closer....
