Adhesive to hold Speaker crossover components
I'm replacing a couple of capacitors in speaker crossover.
The parts have a glue that holds them tight to the PCB, the glue is still a little bit rubbery after 33 years. (Pioneer HPM-700) What can I use that will do the same job, without solvent damage to the electronic parts? Mikek |

That's what I use for heavier components subject to vibration. eg... http://uk.farnell.com/dow-corning/31...90ml/dp/537007 Cheers -- Syd |

Mikek Thanks Guys, A 10 minute search and a phone call to the wife, I just had to dig deeper into where I thought the hot glue was. Mikek |

Expectations. I was looking for the orange power cord. It was in a bookcase behind other items, in a bag. I couldn't see the orange cord through the bag. In other words, it was my wife's fault!

Lexel Adhesive Caulk read the fine print. can use on polycarbonate as I did, so most anything it sticks to and remains slightly flexible. --- news://freenews.netfront.net/ - complaints: --- |

I mean I have seen RTV and hot melt, but there are some that use some yellowish "caulk" type stuff that is a bit more turgid (for lack of a better term). |

Mikek :-) The caps have been replaced, the speakers work. I think! This a 4 way speaker with the super tweeter crossover frequency at 12kHz. I can't hear past 11kHz. I plan on selling these speakers, so I want to verify they do operate. I did verify operation out of the cabinet driving the super tweeters with a signal generator. I need to hook my sig gen to my amp and listen to the super tweeter with a mic and scope while in the cabinet. Where is teenager when you need one? Mikek |

You might try an SPL meter, or perhaps your wife hasn't read this thread and will help? ;-) You might try measuring the impedance of the speaker assembly across the audio band, too. You should be able to see the crossover and tweeter. Where is teenager when you need one? Save them for setting clocks. ;-) |

Mikek Feed the amp with the sig gen to spot the crossover points. Drive with no more than 150mV |

Mikek Lexel lives on the top of RV's, but is used for gluing tupper ware together...that is there should be a hard solvent process in there...see the MSDS. here's Allied: http://www.alliedelec.com/chemicals-adhesives/ |
