fizzicato Posted December 18, 2008 Report Share Posted December 18, 2008 One year later, i´m returnig to finish my MBFM. Past year i built 3 cores and 2 OP3 modules, but allways was the same problem, lot of noise, only running 2 outputs and hanging sounds (i only eared the rhodes one). Then the only module that was common to all the possibles connectios between the modules was the PSU. Then i have decide to change it. It was a nice "25 Watt Single and Multiple Output" PSU, but im sure that anything was wrong in it, because all my voltage testings were allways right, but at the end... something don´t run. I have seen this from pollin:http://www.pollin.de/shop/shop.php?cf=detail.php&pg=OA==&a=MTgyOTQ2OTk=&w=Njk1OTc5&ts=0My dude is: What is the "2 A - 1´5 A and 0,3 A" behind the +5v, +12V and -12V....Should this work??I have found this one too:http://www.pollin.com/shop/shop.php?cf=detail.php&pg=OA==&a=MzYyOTQ2OTk=&w=Njk1OTc5&ts=20Maybe is this last better because of common 3 A, behind the +12 and -12 vSorry for this (maybe) silly questions....I want to finish my MBFM one day :-(Thanks Quote Link to comment Share on other sites More sharing options...
nILS Posted December 18, 2008 Report Share Posted December 18, 2008 I'm in a rush so I am only answering a part of the q: Both PSUs you linked to are cheap switching supplies (Schaltnetzteile) which are generally not a good thing to use in audio applications (like the SID or FM) as they tend to introduce lots of noisey and audible voltages spikes.
