The company is no longer in business...As a further note, the supplies showed up in Radio Shack sometime later where everyone who purchased one of the boards got to see the problem for themselves. At least R.S. was smart enough to label them as surplus...

Folks:A local discussion has 'erupted' regarding switching poser supplies and whether they can fail in an UNregulated (e.g. high) output voltage condition, or ifwhen they fail will they (almost) always fail in a NO OUTPUT mode?I think this discussion may have been started as a result of a subject here on the reflector about overvoltage protection (OVP), but it's managed to take on a life of its own with respect to the MODES in which a switching P/ S can/will fail.Anyone have enough real experience to express their thoughts on this subject.Must admit... I have no clue myself. I've 'heard' that most switchers fail inthe NO OUTPUT mode, but this is strictly hearsay.Let's try to get several responses and the let the subject drop before IT takes on a life of its own on the reflector and Eric has to step in... he's busy enoughright now. <G> 73, Tom N0SS _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
