illogik Posted April 3, 2006 Report Share Posted April 3, 2006 Than i have one more question because i was thinking of using the PSU from my C64, can i measure the 9V AC comming out of the adapter? Couse i can find the 5V DC but not the 9V AC?you have a digital multimeter? put it on AC ;) (this symbol; ~)or read this topic:http://www.midibox.org/forum/index.php?topic=4850.0and if you didn't know allready; use this circuit; it has a real good signal to noise ratiohttp://www.ucapps.de/mbhp/mbhp_4xsid_c64_psu_optimized.pdfcheers Quote Link to comment Share on other sites More sharing options...

TK. Posted April 4, 2006 Report Share Posted April 4, 2006 The files (>700k, very good picture quality) can now be downloaded here:http://www.midibox.org/users/freaksomnia/PICT0002.JPGhttp://www.midibox.org/users/freaksomnia/PICT0003.JPGhttp://www.midibox.org/users/freaksomnia/PICT0005.JPGhttp://www.midibox.org/users/freaksomnia/PICT0010.JPGHere some smaller versions with remarks:1: the core module has some bad solderings (loose connections), which could lead to failures. There are also missing solderings (e.g. 33pF cap below crystal). I would propose to solder each pad again, the soldering guide in the Wiki gives some useful tips2: the legs of the caps should be cutted, otherwise they can cause a short circuit which can damage the PIC!3: this seems to be a bad ground connection directly at the 78xx - it can lead to the wrong voltage. Here the same: just solder the pads again, it will helpAnd also cut the long cap legs, the danger for shorts is too highBest Regards, Thorsten.P.S.: I don't want to bother you, but do you allow me to bring the two pictures into the wiki in order to explain other newbies, for what they have to take care about?
