If your trigger generator doesn't work well it should at least make sounds. Better check other part of circuit.

is based on eric archer TR 808 DB clone schematics ?
nope, this is based on the original schematics from the URL in the description.
So you've gotta use AC trigger? Doesn't just 4017 counter do it's trick?

Great. If you change the value of the decay pot can you make it longer or is it more complicated?
