Hello friends,
I’m sharing two stripboard designs that I created, both the Doepfer A-151 and the Fonitronik Sequential Switch work very well for me.
I had no success with the Fonitronic with a Chinese CD4017BE, but with an original part from Reichelt.de it worked perfectly. I got the DG412 from Aliexpress which works just as well as the one from Vishay which I also tested.
There are no decoupling capacitors (100N) for the ICs shown on the stripboard design of the A-151, you have to / can add them later!
I added the manual reset push as a mod, works great, the manual clock mod via push button doesn’t work!
