Re: Juno 106 - wierd distortion fault

I "borrowed" one from a scrap MKS-30 I have. I want to replace it. I see some in Chile, may take a chance on that. Expensive though... $60 per. And 2-4 weeks for delivery.

Do you know of a source?

Re: Juno 106 - wierd distortion fault

Mooger5, Thanks so much, Solved. I simply inspected the board, and decided to resolder all the point, and finish recapping near the output stage. When completed, powered up, and clean as a whistle. Your suggestions were much appreciated! EDIT: Yes, I have the addition black wire soldered to the AG-T...

Re: Juno 106 - wierd distortion fault

Ok, checked +15v at C19 only reads 14.35v (This is the same on the PSU board on the +15v test point. Manual says +- 0.8v is ok... -15v on the dot at R68 & 69. Analog Ground is good at C18, Tr7 & 8. I tested the surrounding diodes (6,7 & 8) without desoldering, and seem to be ok, break nice at .56v. ...

Re: Juno 106 - wierd distortion fault

Ok, I pulled tr7 and tr8, and bingo, perfect sound... no crackling.

So I:
  • Resolered all the nearby joints.
  • Replaced C18 and C19.
  • Replaced TR9
UHG, crackling when TR7 and 8 are returned in. Should I check the surrounding diodes for failure?

Thanks Mooger5

Re: Juno 106 - wierd distortion fault

Hi, I have an early 106 with a similar problem. Hissy chorus as well as some output crackling only when the chorus is engaged. I solved the hiss issue by replacing the BBD 3009. But, I still get the crackling. I scoped the output by tracing along the patch. I get a clean output through to the outs o...
