Roland Juno 106 (#6)

Roland Juno 106

After I finished actually working on this Juno, I finally caved in to my perverse scientific curiosity and decided to see if I could use parts from a few half-failed Juno chips (ones from various Juno 106s I’ve worked on, that weren’t fully restored by the soaking/stripping process) to create some fully-functioning ones.

Roland Jupiter 6 – calibration tips

The Jupiter 6 is one of Roland’s two most beloved 80’s polysynths, the other being the Jupiter 8. While I was looking for service documents for the Jupiter 6 though, I came across some absurdly aggressive forum posts from people who don’t like this synth and are pointlessly mad that a lot of other people like it a lot.

I just finished restoring the electronics on this beautiful Juno I bought directly from Japan, with all its voice cards failing, to restore and sell.  I was going to announce it as “for sale” here on the blog, but I had already posted it on our Reverb shop yesterday, and by the time I checked my email today it was already sold.

Another Juno 106. This one, miraculously, had all of its panel switches working! It had not had such a hard life as many others.  Only one voice chip was failing but we opted to restore all of them. It’s best not to give them a chance to get worse.  I pretty much always do all of them now. Continue reading “Roland Juno 106 (#4)”

When I started working on it, this JX-3P looked like a feral synthesizer that had lived in the forest.  It was rusty, the legends had been scraped off in many places, the plywood bottom piece was rotting requiring it to be held together with tape, and it was spattered with literal mud.  It had also been subjected to one of the strangest DIY repair attempts I’ve seen yet.  Someone tried to overcome some bad key contacts by squirting some of that yellow expanding spray foam insulation stuff into the tops of a few of the rubber key contact strips.  Guess what… it didn’t work.

I missed documenting a couple repairs before I sent them home due to an Iphone/kitten mishap that left me without a way to take photos. Now I’m back with another Juno 106 repair.  I finished repairing this one just as another client dropped off another Juno 106.  They never stop coming! Continue reading “Roland Juno 106 (#2)”
