Of course.  Silly me sitting here looking at only the audio section of the
thing.  The modulation section of the schematic does indeed have a 3340
along with CMOS 4046 and 4041, and of course some op amps.

I certainly would never build from this schematic especially when Paul is
making us such a super one.  However, the good news is that Paul's December
sale has reduced the price of CEM chips.  :-)

I was looking to see if I could identify the feature that Dave was talking
about.  It isn't jumping out at me.  But then, I don't see as well as I
used to. :-)
