[sdiy] Humans are not Becoming Smaller

[laxt57 at aol.com]

 Hi Ian
  Well what I am planning is this. A OTA made with SMD that
 will fit the footprint of a ca3080. By input I guess I was not 
 asking about the design of the OTA itself, all that is freely
 available on the web. I guess my question is with the available
 smd devices 847s,3904 etc do you think this sdiy do able?

Of course. I was just wondering what you were planning. :-) 
 
I needed very accurate OTAs for my chaos box. I built a discrete OTA circuit with pretty good parts (MAT transistors) but I couldn't do any better for offset and feedthrough than with 3280s. I'd love to hear ideas for doing better than that.
