<DIV><FONT face=Arial size=2>has anybody had any experience with
TomG's keyboard converter, the kbd2e? I recently put one of these together,
and am getting some strange results. </FONT></DIV>

<DIV>I noticed 4 or 5 discrepancies between the schematic and the pcb, and i
believe I have corrected these. also, i noticed 2 discrepancies between the
parts list and the schematic, and I think I got those right as well. the pitch
CV out seems to be working fine, but the Gate out is acting weird--with key up I
see about 14 volts, and with key down I'm getting a ~4volt p-p square wave
centered around 12v, and from what i can see it has a frequency of around
50 KHz. tracing back a bit i'm reading a 30V p-p square wave on pin 5 of U3 (a
13600) at the same frequency.</DIV>
<DIV> </DIV>
<DIV>any thoughts as to what i should check next?</DIV></BODY></HTML>
