A-107 Morphing Filter Core?

A-107 Morphing Filter Core?

2005-11-04 by vtl5c3

What does the 107 use for its filter core?  Does it use a CEM IC or some sort of common 
OTA (LM13600, CA3280, etc...)?

I don't have one of these (yet!), but from a thread a few months ago 
(message no. 8819 etc.), I believe it is a CEM3379 chip, as also used 
in the 109. I was disappointed in the week not to be able to pick one 
of these up (the UK distributor had run out), otherwise I would be able 
to give you a more definitive answer!

Thanks!  Judging by the sound samples on the selfoscillate website, I'm not surprised.  It's 
a very clean sounding filter.

Now, if I could figure out what the mystery chip is in my 106...  Looks like someone 
sanded off the markings.
