! ! 8. C7 .1-uF monolithic (.1 or 104)
Locate the two 47-pF monolithic capacitors (47 or 470). Do not use the 47-pF
disc ceramic at this point! Install and solder at the following locations:
! ! 9. C8 47-pF monolithic (47 or 470)
! ! 10. C9 47-pF monolithic (47 or 470)
! ! 11. Locate the 47-pF (47 or 470) ceramic disc capacitor. Install and
solder at location C3.
Locate the two 12-pF monolithic capacitors (12 or 120). Install and solder at the
following locations:
! ! 12. C1 12-pF monolithic (12 or 120)
! ! 13. C2 12-pF monolithic (12 or 120)
Phase 3: Jumpers/IC Sockets and Chips
Select a scrap capacitor lead end for use as a jumper wire, as shown below. Use
needle-nose pliers to form to fit, making sure the jumper lies flat on the PC
board when installed:

! ! 1. Prepare, install, and solder a jumper wire at JMP2.
Locate the 8-pin DIP integrated IC socket. Note that the socket is “keyed”, and
should be installed with its key aligned to the silk-screened outline on the PC
board.
