Got this from Bjorn yesterday, thought I should share..Sorry, my build is a little delayed, trying to finish a paper for school.
Hi John,
I don't have time to log in a post but here you go.
DC input goes to battery clip or DC jack
The two points for B+ just connects on pcb ( it just makes a messy drawing unless dividing the points)
B+ on IC is pin 6
Pin 4 on IC goes to ground
This is single supply operated circuit and you can use a powersupply ranging from 6V to 20V but be very ware of output swing if supply is raised higher than 9V's.
50K C
C is the japanese and european suffix for antilog also known as reverselog.
This pot 50KC can be had from smallbearelec

the 47nF input cap is a plastic film suggested Mouser partnumber:
505-MKS2.047/63/10
the littlenote on the side of the cap in the schematic is an M and denotes in my own program a plasticfilm capacitor and you will find a similar small letter on the other two small caps 560pF and 100pF 'G' which denotes in my own program Glimmer or Mica but ceramic will actually do just fine.
I'd think several would be waiting to hear what this one sounds like and it's a simple build and requires no precautions and works every time so it should make a fine folk project
Have fun
BJ
