I have (3) EFM VCO4D modules that use a heated 3046 array.  I couldn't get
my hands on the required tempcos at the time, so I decided to use the
heated expo option.  They work fine and track well... the only problem is
the 10 or 15 minute "warm up" that the synth needs before the oscillators
become stable.  Otherwise, this technique works fine.
