Building a small clone
I resently gained access to some sad1024a delay chips and was thinking about building a small clone.  
I purchased a schematic but then learned that there was a mistake in one of the component values.I wanted to know is if anyone knew what the problem was and how to fix it?  
 
Thanks

I have a schematic for the re-issue which I went through with the vintage schematic and corrected. I suppose you could just swap the MN for the SA and see what happens.  
 
My scanner is currently down, but when it is functioning, I can send it to you. Drop me a line sometime.

Whoa!!
That's one expensive and rare chip to act impulsively with. The SAD and MN may well possess the same number of stages, so they are *functionally interchangeable* but they are NOT *electronically* interchangeable.  
 
What until the schematic arrives.

Re: Building a small clone
I was also wondering if anyone had a pcb for the small clone because I'm not the best at designing them.
