    Hello to Nick and all forum members.  It has been a long time since I posted here but I have browsed the forum without logging in.  I’m posting now to share a photo of my second DINAS build and ask for some help with a problem I’m having with one of the DINAS.

    A little history.  The DINAS were my first build.  Building them was a lot of fun and they sounded great.  I learned a lot building them. Since my first build I have built another five pairs of speakers, two subwoofers and a center channel.  While I’m not a Japanese master craftsman, I like to think I gained skill with each build.  Here’s a photo of my first DINAS:


    Why did I build another pair?  Glad you asked.  I “loaned ” these to a friend and he likes them so much I can’t ask for them back.  Feeling a need to upgrade my computer speakers, I decided to build another pair.  I could go on longer but I’ll just post  a photo.

    This photo was take shortly after I made the last solder connections.  The one that is working sounds fantastic.  This brings me to my request for help.  I am more of a wood worker than an electronics person. Fortunately I can follow instructions and solder the connections.  However, I made the mistake of testing the first speaker the same way I test my passive builds and sent an amplified signal through the plate amp and to the drivers.  Now the only sound I get from it is a thumping heartbeat type sound.  I’ve retouched the solder connections and they look good.

    I’m looking for guidance and suggestions.  How can I test the plate amp to confirm it should be replaced?  I think the drivers are ok but I’m not sure.

    Suggestions and comments greatly appreciated.
