[sdiy] saw to tri/sine options

[Aaron Lanterman]

There's also the Buchla converter, which uses a cuople of resistors, a  
couple of diodes, and a FET. You see it all over his designs. (I think  
that circuit predates Buchla, though. I recall seeing it discussed in  
Hal Chamberlin's book, but I don't have it handy at the moment to  
check.)
