Looking at the Fuzz Aldrin, the documentation says BC109 transistors. Looking at @Chuck D. Bones guide to Lunar Module / Screw Driver / Hybrid Fuzz Drive modifications, BC109C is listed. Does it matter which is used?
Also, the modicum of web searching I did suggests that BC549 is a modern equivalent (read: readily available, cheap) replacement for BC109. Would that work as well in these circuits?
While I'm at it, Chuck also suggested AC127 for the germanium transistor. Small Bear has these... at $4 a pop! Is there a modern equivalent or "close enough" part that will work here?
