Lin VCA DIY

2005-01-05 by Nicholas Keller

Hello,

 I hope all are having a great new year so far.  I got my some 
modules from the US rep so I'm happy (137, 156).

  However, I've tried several times to make a simple linear VCA based 
on a 3080 design from a Midwest Analog book.....  it never works.  If 
someone on the forum has the knowledge and patience to review my PCB 
in image form along with a version of the schematic, I'd appreciate 
it.  I'm getting no reply from the Midwest staff.  I plan to post the 
pics on one of those photo host sites, or I can email directly.

 Or if someone can direct me to another VCA plan on the web, one that 
you know works, that would be cool too.  No CEM/SSMs please.  I'm 
working with +/-15V.  I've also tried the ASM-1 VCA, no luck.     

Thanks,

Nick Keller
