Trimming
|
This circuit requires no
trimming. It must work when powered on. NOTE : after powering up, the module needs at least ten clock cycles before it gets into the expected behaviour. |
Modifications of the old PCB
|
NOTE : these modifications are only
for those who built the circuit with the old PCB
Remove the long strap between the
collector of Q1 (lowest transistor on the layout) and pin 3 of U1
(4006).
With an sharp knife cut the short track from pad 13 of U3 (4070), connect a short isolated wire between pad 11 of U3 and pad 3 of U1, connect a short isolated wire between pad 13 of U3 and the collector of Q1. |
