    Saddened by your loss; buoyed by your son’s wedding.

    What are these

    They look like a cross between Klipschorns and something from JBL.

    Bluetooth "iPod" Dock on Steroids

    This did not go well. Smoke and flames accompanied the music upon initial testing. That tells me the amp is OK, but the Bluetooth and/or volume control boards could be toast. I removed everything from the enclosure. Fortunately I have extras of all three boards. I will rewire everything and make it better than ever.

    Bluetooth "iPod" Dock on Steroids

    I got the battery McGyvered back into place before dark, but the rest of the reassembly must wait until Fathers’ Day.

    Bluetooth "iPod" Dock on Steroids

    Did you ever start a project and then quickly regret it, but it’s too late to stop now? The boombox needed the sealed lead acid (SLA) battery to be replaced. After many charging cycles, it will no longer fully recharge to 12v; ~ 10v is max and it discharges too quickly. The good news is, I just happen to have 4 SLA batteries. The bad news is, the new batteries are slightly taller. I can McGyver it into place, but a trip to a real wooden floor hardware store is needed to get the bits needed to make it work. Replacing the battery requires a complete disassembly. Who designed this damned thing? Oh yea, I did. Never mind.

    Now they’re done. The screw eyes are bolted in place with fender washers and split washers. The safety cables will be as short as possible to minimize the shock load in the unlikely event they’re pressed into service. Of course, the screw eyes will be near the tops when gravity is holding the female parts of the speaker on the male posts on the brackets. Excuse me, I need a cold shower. Cat Stevens’ Tea For The Tillerman sounds very good out on my deck. Don’t be alarmed @CECAA850. The speakers are upside down now so that they’re right side up during testing, but in situ at the school, upside down will be right side up with the exception of the terminal cup which will be upside down when the upside down speakers are installed in the band room. There will be a quiz later.

    My gmarsh designed and built Wiener 3118 board sounds excellent. At the recommendation of Rich, @rhing, on the diyaudio forum, I purchased the board as part of the third group buy. It’s my understanding that the heat sink is the difference between a 3116 and a 3118. As can be seen in the photo, the Wiener does NOT have a heat sink. Gary Marsh (gmarsh) offers a thermal pad that goes under the chip, between the chip and the case. He said he felt it would be unnecessary in my situation, but I figured it couldn’t hurt; he agreed. Because I’ve yet to complete the process of installing my TI TPA3255EVM in a case, I use the Wiener much more often to play the various Heresy derivatives I’m working on for a middle school band, friends, relatives and personal use. Granted it’s used at moderate levels with efficient speakers, but heat has never been an issue. The bottom of the case, which is “connected” to the chip by the thermal pad, has never felt even warm. A reminder, I use the Wiener and 3255 in balanced mode with the balanced outputs of Pono players. That is the reason for the four RCA inputs.

    That’s a great deal on great speakers.

    They are flipped. The speakers are upside down in the photos.

  11. You could always enjoy them now and sell them later when what you really want is available.
