I spent a lot of money putting together a Nava and ultimately failed. I asked here but never got any support from E-Licktronic. I thought I was just impatient and stupid until I managed to put a Gilbert together in ~15 hours on the first try. E-Licktronic’s PCB quality was to blame. I was not willi...

Hi there,

the VCA and waveshaper of your clap seems not to work properly.
check with a scope the shape you have on U23 Pin13

You should find 4.096V.

What Ic is IC3 ? Do you use 4049UBE ?
Here is the layout of IC3 connection. Hope it helps

Great to ear that burning your µC solved the encoder and leds issue. About ground noise it seems that you have a faulty power supply or rail. Disconnect the IO board power supply connector and check +15V, -15V and +5V rails. Then check PSU capacitor way on the mainboard: C12,C13,C24*,C25*,C26*,C27*,...

I now have discovered that it makes no difference if the Atmega controller is in the socket or not. All the LEDs are continuously on when the power is on. However when I quickly turn off and on again, only part of the LEDs will be on. Maybe this is a clue to one of you guys? Test Digital Ground and...
