<div class="moz-cite-prefix">Hello Al<br>
Welcome to the group!<br>
<br>
If the voltages at the potentiometers are ok, then the only two
possibilities I see is are either the 4558 (IC14 - causing some
number overrun inside the D/A if to much voltage is sent) or (more
ugly) the YM26700 itself (IC11).<br>
<br>
The 4558 is easy to replace, the YM26700 is quite an unobtainium<br>

HI all,
<div>This is my first email to the group, hopefully I'm doing it
right!</div>
<div>I am working on a CS-60 that has a strange issue with the
Brillance controllers on the right. They LO lever seems to work
correctly. However the HI lever changes the pitch of the notes
when you pull the lever down. It shifts the pitch up as well as
adding unwanted artifacts to the sound. I'm scratching my head
as to why this might be happening. I'm assuming something is
going wrong in the KBC circuit.</div>
<div>Does anybody have any ideas?</div>
<div>Thanks</div>
<div>Best</div>
<div>Al</div>

</div>
