CA3280 OTA replacing LM13700???

[chicago_mike]

  Hey all, I have a couple of diy projects that use the lm13600/13700. I have a handful of the CA3280's wich I think are the same thing prtty much. Can I use these instead?

Thanks!

Rick, thanks for the link to Don Tillman's blog.  VERY interesting reading and a nice and transparent introduction to the mysteries of why some things remain available while others disappear.  Even if one has no interest in OTAs, excellent reading.
