I took some additional pics and posted to the same album. Looks like there is at least 1 leaky cap. Take a look at this photo: http://launch.ph.groups.yahoo.com/group/emlsynth/photos/view/d021?b=6&m=f&o=0 So, do you think I should just swap out all the caps on the PSU to be certain? > -----Original Message----- > From: sasha > Sent: Tuesday, February 05, 2008 10:01 PM > To: 'emlsynth@yahoogroups.com' > Subject: RE: [emlsynth] EML 100 > > Hi David, > > Thanks so much for your reply. > > I have tried plugging into all the outputs and get absolutely no sound. > Do you think it's likely that the capacitors on the power supply are > shot?
