Hi,

I've been defeated by this one... Pics below (it was so pretty when it was in the enclosure *cries*).


From what I can tell the main board is doing it's thing. I can see things pulsing away on the wire side of IC2. Broddling around I can find the speed working also. Just nothing on the knob-board... The signal is going through the circuit and coming out the other side... But with no effect applied to it.

I'm a bit stuck on this. Any ideas? Gonna attack it again tomorrow anyhow, but pointers of where to look would be most welcome.

First, I'm pretty sure your pots are backwards, unless that type has a totally different pinout.

Try swapping the direction of one of those pots, and maybe its adjoining LED....it could be backwards, too.

can you tell if it's sequencing through the different knobs? if it is, then you know that the problem is in the filter block.

if it's not sequencing, does it apply the filter from the first knob? if it's not, you might have a problem with the decade counter.

Reversing the LEDs has sorted it! Cheers MB!
