Midwest Audio Fest

It’s that time audio enthusiasts! Registration for the 2019 Speaker Design Competition is now open! Visit midwestaudiofest.com for details and to list your speaker project. We are excited to see all returning participants, and look forward to meeting some new designers this year, as well! Be sure your plans include a visit to the Parts Express Tent Sale for the lowest prices of the year, and the Audio Swap Meet where you can buy and trade with other audio fans. We hope to see you this summer! Vivian and Jill

  • OT: transformer

    I have a salt generator on my pool. Not working. I've gone through the recommended diagnostics and all voltages check out, except the instructions suggest that the resistance on the two legs of the transformer should be 2.1-2.9 ohms. One of the pair measures 2.7 and the other pair is 3.1. Is that fair enough out of range for this system not to work?. I believe the board is running at 24 volts and the voltage supplied (when generating chlorine is supposed to be between 15-24 volts. thanks

    I don't think the transformer is bad. A bad reading would be a short curcuit (a few tenths of an Ohm) or an open circuit (very high resistance).

      your right, the reading dropped from 3.1 to 2.7 when I scraped the corrosion off the terminal. thanks

        I believe those systems use a cell (electrolysis) to break apart the NaCl molecule. That requires DC current. So if your transformer tests good the problem could be the rectifier(s) that convert the AC to DC. If that's not it maybe the cell has failed in some way.
