You compacters everywhere: We are beginning to see a few questions here about a variety of dysfunctions with Classic IIs ranging from crackling audio, memory management, startup problems and others. Being in the midst of setting up seventeen Classic IIs all as one project, I am seeing a pattern here. Simply, each Classic II that has a non-software problem has shown the same leakage of capacitor goo onto the motherboard. Sometimes the leakage is obvious. Sometimes you gotta look close around ALL of those tiny aluminum can capacitors. There are maybe four or so "farms" of them about the 'board with a few strays. Just a dulling of the normally bright green substrate is all you need to know cleanup time is here. In all but one case, a thorough cleaning of this goo restored the 'board to service. I haven't tried the dishwasher yet. I have used liberal amounts of isopropyl alcohol and even more liberal use of Q-tips - gobs of them. Other Classic IIs of this project have shown leakage with no dysfunction. I have two concerns with what I see. First is that if left unattended too, this capacitor goo will etch into the traces and leads to distruction. The second is that these capacitors, as with other compacts, are reaching the limits of their life. For now, clean, Clean, CLEAN! For the future, can we get a spec and source on these caps for their replacement?
