[sdiy] Buchla 259a and LF13331 substitute

[mark verbos]

be careful.

I have worked on many 259s. I own one that was built by a 3rd party  
and this person used DG412s instead of LF13331Ns. In theory, these are  
better, faster, lower on resistance, but they caused little glitches  
that went away when replaced with actual LF13331Ns. I'm not saying  
that there's anything magic about those chips, just be sure to use a  
replacement that is similar spec'ed and not "better."

I recommend DG201 as a replacement in the 259. The pinout is almost  
the same, sadly a couple pins are rearranged.
