If the wall warts are noisy, check Digikey. Jameco, or Mouser. One of them has
non-switching wall warts for about $10.00 or so. I think it's from Jameco so
you may want to check there first

I had two Clack WS1 valve/control heads installed on a newwater softener system
(just 2 tanks for softener and neutralizer asour well water isn't too bad).
Turning off the breaker to the controlheads didn't change any RX profiles, so
they seem to be RFI-quiet. Theyuse small wall-warts (V3186) and the
display/control board is always on(bright color LED screen). Once I get more
ferrite cores I will add themas a precaution.Regards , Kenny
