Hi Guys.
its my turn to give something to the community
i was looking for the TR808 BassDrum over the net and found this site:
http://praxistest.cc/808basedrum/
but i didnt found the layout with no components so i decide to redrew it
its not verified but its exactly the same layout just with no components, i think it should work.
the circuit works with (+)(-)15V, i dont know if it will work with 12V, the pros among us will probably will know better.
all PNP's are 2SA733
all NPN's are 2SC945
it haves...
Volume
tone
accent
trigger
cmos trigger
decay
extra decay
tune
env tune

my redrew layout:
i put my logo in the pcb but the credit goes to Praxistest.cc!
i hope it can help someone here.
cheers,
Isak E.
