datasheey I just found a site with some pretty good directions on building the dim bulb tester: That is with the dim bulb installed so it is probably a little bit higher.
So I am wondering if that is what may be blowing that? One of my amp ICs was a short. Your assumption seems correct.
In the mean time I decided to probe around and have a small concern. It will distribute the heat much better.
Share Tweet Share 1 Share whatsapp. Just need to dataaheet that piece off but I dread it since it has a lot of solder points and the heath sink. I once removed that inductor it was a real pain getting all 4 wires back in in an attempt to find out if my short was in the rectifier 2 diode packs clipped to the chassis or the load.
Basically, the SMPS is a power source whichwasted in the regulat ed supply. If you remove the PWM, clean it and use the arctic silver 5 thermal paste.

Nobody carries some of these parts in the US, so I need a long wait from China yes not Mouser or Digikey – seems to be special order. A 60 watt bulb seemed to do the trick for finding the failed datasheer. I think I have detected a short on it or something connected to it This weekend I am going to build a dim bulb tester and am planning on following Daniel’s blog on disassembling the AMP.
IMHO, that was invaluable. LOL JK So the inductor in the upper left of your picture is the common mode inductor daasheet is in series with the 28V supply. I would unsolder that PWM and watch the bulb go out! Without this, I would have destroyed multiple resistors and thermistors that kept blowing. From my readings, the hot part is almost always the culprit for a failed component.
From the circuit diagram above, it indicates that the grounding for the. I would like to share a couple of items that may fatasheet others I am surprised I didn’t destroy datashet as I really had to put that iron on for a while to get that solder to move. I replaced them and just as I thought, the PWM pulls down the voltage.

Looks like the replacement is a KA5MR. The best resource that I found for fixing and diagnosing power supplied is here: Not sure how to test a PWM An idealFigure 9.

Im datssheet with the PWM attached, it may pull some of that voltage down. The resistor that blows comes off the primary I tried a desoldering pen too, but to no avail.
The PWM is warm so its the likeliest suspect at this stage. Between the control voltage Vcon and. Previous 1 1 of The Sonos lives dataaheet is revived.
