<DIV><FONT face=Arial size=2>Well, I've just successfully completed my synthacon
filter (based on Ken's version of the Steiner circuit). </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I had a little trouble with it, but the main
problem was I had the PN2222s in backwards (doh!) Of course, this was
because I pulled up the datasheet for the 2N2222, which has the reverse
pinout. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I used a 1.5k pot for the resonance control,
partly because I didn't have a 1k, but also, I wanted to go with a slightly
higher value, so I could push it way past oscillation. A 2k would probably
work well also.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>But, I *must* say... what a VCF!
so raspy & gritty... it's fantastic!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have decided to include this as the 2nd VCF in my
suitcase synth project. It should make a perfect compliment to the Moog
style transistor ladder filter.</FONT></DIV>
