Loose terminal boards...

[ Follow Ups ] [ Post Followup ] [ Welborne Labs ] [ FAQ ]

I re-did some wiring on Moondogs this morning, and, upon pulling the bottom plate on the chassis, discovered a total of four terminal boards flopping around inside. All the epoxy or whatever adhesive was originally used had the consistency of a sort of semi-soft candy! If this happens to anyone else, I suggest using recently purchased epoxy, mixed very well. All other boards have the same problem, and are just barely held in place. I plan to repair all of them, but want to spend some time listening this Thanksgiving, as well. It would also be good to lightly clean down to some bare metal before joining glued section; or at least to thoroughly roughen the clear coat before glue application.

The epoxy should hold fine. We've been using it for over 5 years with only a handful of reported problems.
Your problem sounds unique as the epoxy generally becomes brittle over time and not gooey. It could have been a bad batch or possibly we did not mix it well.

  This was a bad batch of epoxy, for sure, Ron. The stuff wasn't any harder than a jelly bean! Also, epoxy does not always adhere well to painted surfaces, so it's really a better practice to apply it to the base metal/surface. And some epoxies are horrible with certain plastics like nylon (standoffs). All of them are pulling off their foundations and will have to be repaired. I would certainly consider drilling the chassis to achieve proper anchoring of the terminal boards, despite the fact that, yeah, a few more screws will be visible from the top. I'm going to do this to my amps when I've the time. I would have been happy to pay a little more in production costs (if that is an issue -- and I can appreciate that)if it would have saved me from doing what I have to do now.

    Well, like I said, we've been using it for years and sold over a thousand of these amps with only a handful problems so I'd say it really isn't a problem and therefore I chose to preserve the cosmetics of the amp than have another dozen screw heads on the surface.

      Alright, Ron. I know you've sold lots of these. Thanks for your help and suggestions for repair (?)

        for patience and understanding (Ron W's, especially). I think I may have made a bigger deal out of the terminal board issue than it really is -- sometimes other issues can color one's overall attitude and tone of voice. I've said this countless times before (including a letter published in Listener), that: Welborne Labs' products are absolutely top-notch; customer service can't be beat, etc., etc. Nearly all the old epoxy has been removed from all the loose terminal boards, and a generous AA inmate (who experienced something similar)has even offered to share matching screws so the boards can be attached more securely.
        I love my Moondogs!

Epoxy will not hold,you have to drill.RTV will adhere to the plates but not to the nylon standoffs.
