Thank you. 
Yes you are correct I intended the "hot" to start around 2,000 
cycles.  If you want lower freqs as well than a larger base is needed 
as well as changing the signal capacitor to .1 uf.  I would like to 
find the exact cap values to give an exact low cutoff.  I was using a 
value based on experience without using the math.  If anyone has the 
math that would be nice.
