[sdiy] quantizer working

[Graham Atkins]

I wasn't suggesting Mouser are bad, but that even with the most  
reliable suppliers,
sometimes a bad batch of components can get through. I always go for  
IC's that are
branded...like Texas or Analog Devices. I know lots of companies sell  
so called
"unbranded" parts but for the small saving in cost it's not worth the  
hassle.
