I was about to give up on it when I noticed hairline cracks around one screw hole in the board. Was able to fix them and then it booted up properly.<br>But it still seemed dead. Until I almost accidentally closed one of the switch contacts with a tool, and it responded. (In fact it’s so snappy I could be lazy and trigger the switches with MIDI via 4066 ics and it would probably respond at a high speed.)<br><br>Looks like very fine hair and dust, like Persian cat dander, is coated around the knobs and switches.<br>So anyway I found this link on polynomial showing how to crack the switches apart and clean them with a q-tip. I have some black goo I used to permanently fix an Alesis MMT-8 and so I intend to coat the rubber contacts with this good stuff.<br><br>But just wondering: Does anyone know what kind of switch this is? (See photo on polynomial Repair Blog). To me it looks too good to not be an Alps, but it’s not a keyboard switch, is it?<br>Whatever it is it’s kinda cool, as long as you don’t have cats.<br><br>It seems like a lot of these kinds of parts have vanished from the storage bins and there’s nothing that would take its place.<br><br>Ben<br>________________________________________________________<br>This is the Synth-diy mailing list<br>Submit email to: Synth-diy@synth-diy.org<br>View archive at: https://synth-diy.org/pipermail/synth-diy/<br>Check your settings at: https://synth-diy.org/mailman/listinfo/synth-diy<br>Selling or trading?
