Silencing Dead Chips on Juno-106

Hey guys,

I have a gig on Saturday, for which i will be using my Juno-106 in Unison mode. Unfortunately one of the two original Roland voice chips she has left has started to die, and there's no time to get a replacement in. Is there some way to use one of the trim pots on the circuit board to silence a faulty chip? It's producing some strange crackles, and i'm worried that it might get stuck on a note in the middle of the set as they tend to do when they're on their way out.

Thanks!

Take it out, take it out, remove it?

I don't believe so. The only thing that comes to mind is the VCA GAIN trim for the respective voice. I figure you're lucky to be able to drop the voice more than 6dB with that though. I can look in the service manual later and see what else you might be able to do without damaging anything else.

When you can buy VAs for 400 dollars or less, that will emulate the Juno sound pretty well, it's kind of a non-brainer to leave the Juno in the studio where it will really shine, and take a VA on the road, where the audience won't really hear the difference. Juno 106 is too unreliable a board to play live without a backup.

VCA GAIN won't work, as the VCA is in the failing chip. The only way to truly silence the chip is to remove it.

But ChristianRock's advice is sound advice, get a VA synth to take on the road.

Lol, i'm just doign a tiny set in my apartment for some friends so hopefully the Juno will suffice for the time being. So if i remove the dying chip, the rest of the Juno will still work fine, even though there's a big hole where one of the chips should be?

Yes. I've done this to multiple MKS-30s and a Juno-106.

Ok, thanks guys!
