ASM-1 was designed while running +/- 12v, then optimized for +/- 15 later.
So yes it will run on bipolar 12 volts. It will probably go even lower, like
bipolar 10, but I haven't tried that and some component values would probabaly
have to change to keep things like VCO scales correct. But 12 volts is
fine!</SPAN></FONT></DIV>

than that I can offer no advice - I really appreciate the comment about
challenges because that's how I got started! My original PCB's for the
Electronotes ENS-74 from Wasatch Music were a mess when I first built them. (I
remember trying to figure out how a portamento circuit worked. I though that if
you ran audio through it then portamento would be added to the music!!!) Anyway
my VCO's were blobs of solder on the bottom and flux everywhere and overheated
chips and so on. But I was possessed by the need to have a working synthesizer
so I kept at it. The stuff I played with in the music stores was just too
bitchen to believe. I remember Springfield music in Northridge CA had a Mini
Korg and a Synthacon.... changed my life...</SPAN></FONT></DIV>

<DIV><FONT size=2>I bet I'll get loads of "What did I said"
messages.</FONT></DIV>
<DIV><FONT size=2>Ok... My ASM VCO is silent. I've checked the connections and
transistor/fet polarities. Everything seems to be ok but still I don't get any
signals out. I'll get -8V out from saw output and -2V out from pulse
output. </FONT>I think the problem might be my 12V power. I know
that ASM is for 15V. Does ASM work with 12V without component changes
or do I have to change any component values or is my project
doomed?</DIV>
<DIV> </DIV>
<DIV>P.S. Answer is still no. I don't want to buy kits even this is tough. I
like challenges.</FONT></DIV></DIV></BLOCKQUOTE></BODY></HTML>
