This one's gotten a fair amount of hype over the years. It's essentially a Timmy without the bass control and a few different values. The IC and clipping diodes haven't been confirmed, other than 2 silicon, 2 germanium. 1N4148 and 1N34A should get you pretty darn close. IC is just a dual op-amp so socket and audition your favorites. Schematic here for reference.
