Juno 106 Question

[Synthfool at aol.com]

The Juno 106 had a bad production lot of 80017A VCF/VCA hybrid IC's in them.
The lot number was 41 and was printed on the side of these chips. There was
also a small run of bad waveshaper IC's, part number MC5534A, but I haven't
got the lot number offhand. I think it was 54, though.

When a Juno 106 makes a weak or nonexistant sound every sixth note, it is
usually one of these chips. But, if it sounds just slightly "off", especially
on high resonance patches, it may only be an internal filter trim that is
needed.
