Problems with my Stripboard-Sequencer (Baby-10)

[Juno60]

Hello @ all,

for my DIY modular I made a stripboard layout of a simple 8-step sequencer. It's basicly a baby-10 sequencer. I added manual step, -reset as done by Fonik and a simple 555-clock.
But I guess there's something wrong, 'cause ist does not work. Can anyone please check my layout?

The internal Clock goes by a int./ext. switch on the panel to Ken Stones Gate2Trigger converter. The converters signal feeds the 4017 clock input.
When powering the sequencer several LEDs are lightend (not only the active step) and neither the internal, nor an external clock signal seem to affect the sequencer.

I built a baby-10 sequencer a year ago without any add-ons and it worked fine. So I guess there must be a mistake in the clock-input circuit. Maybe you can figure out what is wrong with that layout.

Thx a lot!

Chris

When somthing goes wrong with a stripboard, check the power supply voltage

You might be getting inteference on the switch .... i.e mains hum and its going at 60hz

check / re-solder the switch connections.

does manual step work?

last resort try replacing the 4017
