I did some more digging and found this photo of what appears to be a prototype A-150 LFO, although I don't know if it's legitimate: http://www.synthforum.nl/forums/attachment.php attachmentid=48037&d=1243454799 Perhaps you can shed some light :) Sorry, I just find prototypes interesting, that period when you were first brainstorming and tweaking what became the first A-100 modules.
