hi, i have been through eight 6581s and two 6582s and so far every single one of them are showing faulty filters when testing them with my midibox very loud background noise when filters are activated, and the oscs are extremely quiet, almost inaudible. is it possible i have done something wrong in the build? i have made sure the jumpers are correct, i am using a regulated 12 volt supply, i have checked the voltage at all the points, and i cannot see anything wrong of the sids i have tested, 4 of them were supposedly tested. i just got two from the folks at hardsid. the other 4 sids, i was given for free and figured they were most likely faulty. has anyone heard of a mistake that could be blowing the filters? i dont want to keep trying sids if there is a chance there is a problem with the build....

cool, i'll keep searching for SIDs. thanks for the help!

thats what i thought, but i have tried 5 different 6581s now. each time, the osc's get much quieter when the filter is applied. maybe i am just unlucky?

My sammichSID is getting 12.1 volts where it is supposed to be getting exactly 12. i am using a regulated power supply. my question is, will this cause problems? i have tried one 6581, and the filter did not work. i dont know if the filter was blown to start with though. could this voltage difference be causing the filter to not work right?
