Dexter power supply problem found

I am sorry to report that we have discovered a problem with some of the power supplies which I have shipped out with Dexter.

They look like this:


The symptoms include a buzzing hum heard over the game speakers and possible lock-ups of Dexter itself where the system needs to be restarted.

Here are two replacement power supplies that I've tested and verified work much better:

  1. Will the dexter that where suppose to be shipped be delayed or are they still shiping?

    1. Yes, this has delayed shipping although I have tried to keep up with preparing orders. I have a large number of boxes just sitting in my home waiting for new power supplies.

  2. Have users tried installing a high value filter cap in parallel with the power supply as a work around? That should help with voltage ripple and power dropouts

  4. I recieved my Dexter in the mail several weeks ago, & only now had an opportunity to spend some time to hook it up. My adapter is not the one pictured, but I do experience the hum in my speakers & the dexter does not boot up. I hear a couple of game noises when I power it up (a beep, a long pause & another beep, then a long pause & a boop), & some white text appears in the top left corner for a fraction of a second while that is going on. I have the Hi-tech card installed in my machine which was running my Pioneer laser disc player with the limited edition laser disc & roms. Not sure if any of those things could cause the problems, but I figured it's worth mentioning.
