Hi all. I've got a trouble with my EMax S.E. The sampler was "power off" but anyway when, by a sunny morning, i tried to switch it on ... Nothing ! My first action was to unscrew the machine and check fuses and others "mechanic" (wire connexion, ...) possibilities. But with success ... So i've tested the internal PSU and noticed the +5V was down. It seems that there are 2 faulty components : - Capacitor (22000 microFarad - 10V) : Electrolytic - Triac (2 diodes, common cathod) but i cannot find any piece of information on this element ... :( The element is screw on a little thermal dissipator with 3 pins and the reference is : C 1 0 P 0 3 8 (and a little code in the right up corner : IR4J). I guest it's just a dual diode redressor with a common cathod (centered pin) but i cannot find specifications... Maybe 10A... And this element is in the low-voltage part of the PSU (10V ... Maybe 12V). Any clue ? Thanks a lot Jean-Marc. -- Jean-Marc http://www.moderncubism.com
