Buchla 258 Sawtooth
Well after a lot of mucking around and changing the FET's quite a few times we have the "sawtooth" that looks pretty much like the one that was captured from the original.
This was a picture that is from the synthesis technology website. I tried linking directly to it but the Blogging software didn't work so I have copied it here. You can see all the original information at Synthesis Technology.
Mark Verbos, from who's design & PCB layout i used, has also done a more accurate clone from which he garnered this picture:
You can read his full blog posting here. Strangely I did end up securing the original FET that Don used, a 2N4339...
