Re: My Source is crazy, but in a catatonic sort of way

Hey All, the problem is definitely related to the memory, I think perhaps one of my RAM chips has kicked the bucket. Swapping the RAM yields a new set of tunings across the patches every time. But, they do correctly store all the patch info, and the level 2 functions all work, so maybe not. So many ...

Re: My Source is crazy, but in a catatonic sort of way

Well, I'm back. This Source clearly intends to test me heavily. New issue, not entirely crippling, but highly vexing. After a month of lightly gigging the synth, I sat down last night to do a bass line on a recording project. Much to my dismay, the synth is now greatly varying in pitch from patch to...

Re: My Source is crazy, but in a catatonic sort of way

I just came back from being on the road all weekend. I'd given all the leads of the membrane panel a good coat of conductive ink prior to getting in the van. Total success. All membrane buttons are doing what they are supposed to. I'm not sure how long this fix will last, but for the here and now I'...

Re: My Source is crazy, but in a catatonic sort of way

As a last ditch effort for my membrane connectors, I bought one of those conductive ink pens that I have scoffed at for years. Much to my surprise, it has brought back much of the membrane function. I don't want to jinx it, but I may be able to turn it around. At this point I feel like a doctor who ...

Re: My Source is crazy, but in a catatonic sort of way

Hey everybody. Much as MC predicted, my Source has proved to be quite the handyman special indeed. After reviving it with a new processor, I found that osc 1 was jittering in pitch pretty badly after about five minutes warmup time. This was traced to a bad 358 opamp, U35 on the synth board. After th...

Re: My Source is crazy, but in a catatonic sort of way

The random patches are probably due to the battery back-up being depleted Alien, In most cases I would agree, but here I think the patches got scrambled because I popped out the ram. Whoever serviced the synth a while back put a new battery in there. Source saves patches fine. I'm preparing to do b...

Re: My Source is crazy, but in a catatonic sort of way

Hey all. My source is back in the land of the living. The Z80 failed. I went over to an old friends house today to work on the keyboard. He has all the test equipment one could ever want. The cpu was proved dead in short order. Thankfully this was a way more quick process than I thought it would be...

Re: My Source is crazy, but in a catatonic sort of way

MC, thank you so much for your thoughtful and information packed reply. You are a champion and a warrior for good. Looks like I'm in for a bit of a thrill ride. Does anybody have a line on the eprom code for the source, out of curiosity? I've got OS 2.2 in here. Yes, I do have access to an eprom bur...

Re: My Source is crazy, but in a catatonic sort of way

Hey Guys, Thanks so much for the replies!!!! I'm not the most experienced synth tech, but I'm actually a very qualified tech for wurlitzer electronic pianos, rhodes suitcase, and the like. I do an awful lot of soldering for money, and would actually call myself a good judge of other techs work. The ...

My Source is crazy, but in a catatonic sort of way

Hey everybody. So, I've been saving up for a while for a genuine classic Moog. I got an Mg-1 a while ago, but that didn't really cut it. I decided on the source as it sounds great and you can save presets. I have plenty of other synths with tons of sliders, so the wheel is not a deal breaker for me....

Re: Moog/Realistic MG-1 Mod Guide

Hey there. I'm trying to build the noise generator, but I'm a little confused by the schematic. It appears that the collector of q1 has been left open. Is this correct? Thanks so much for doing all this work, this is an awesome trove of information on a cool synth.
