Hi everyone,

I'm looking for some advice before I decide if I just need to send it off for professional repair...

I just finished building my Extra9 kit, hooking everything up, and powered on for a quick test. Unfortunately, the only sound I get now is from the Snare and even it doesn't have any noise, just the oscillator. Every other sound is dead ... the sequencer and controls are all working as expected.

Everything was working perfectly before the Extra9 installation. It seems really strange that everything would be dead all of a sudden. I've checked the power to the Extra9 board and it looks ok.

Is there something obvious that I'm missing? Or something I can check?

Thanks in advance.

Try and narrow it down. Start with just the BD connectors and power to the extra9 board.

Ensure the 4 pin that carries the BD signal is connected to the IO board and the two other cables between main and io board (6 pin and 8 pin) and of course the power cable.

Check you have 15v etc as expected.

You should be able to connect one voice at a time and debug.

Thanks @orbist.

I did that and am just working on the BD now.

The power to all boards looks good.

When I check the test points on the BD I noticed two things:
- The point marked "noise" has no signal (is this related to the lack of noise on the snare as well?)
- The point marked env2 has no signal

The rest show as expected on my scope.

It was all working before, so either something is up with the extra9 board or I broke something on the main board while doing the mods...

Thanks again for all the help.

Maybe worth backing out the wires in the BD section to the extra9 board.

You could add the original components back to the main board by bridging them in the relevant pins in the connector BD2 for example. And add the pins for the attack pot back to the board.

If still no sound, then something broken either in master or io board, or the accent muxes!
