Hi all,
Happy Christmas to you all.
If you are a little bored over christmas ill be excepting advice as to what is wrong with my build.
I Can only just hear a faint click from the Cowbell, Cymbal, Open hat And Closed hat. i was testing continuilty which i feel is good and had TP4 on one end and i was touching around the caps near the bottom ic when i could hear the Cymbal.
I have been messing around and fixed most of my issues as i had a lot but they were just diodes all other components seem ok on the scope and dmm. i did have problems on a couple of resistorss when the anular ring colapsed on a about 4 or 5 but i bridged them and they are fine.
I feel it is a simple fix and its a noise problem but as i am a beginer still ive exhausted all my prodding and could do with some propper advice.
thanks everyone.
Clap, Cb, Cy, Oh, Ch Help please [SOLVED]

Also forgot to mention that the clap is a little low on output to
Did you build the noise section?
yes noise is fine for snare/toms / kick cklick / Maracas and clap just not working in the cowbell and hats and cymbal. seems like white noise as the others or pick noise?
Ok further experimentation brings me to this. i have to take the noise from tp4 to tp5 and tp6 via some solid core hookup cable.
Noise is getting to the snare and toms fine. the only issue is with the hats and cowbell. so could it be a bad cap, week via or trace? transistor? all caps have been checked and are correct orientaion and value. all resistors have been checked are correct values. transistors are correct values and orientation.

With the Help of Vincent my issues were solved. Bad Q9 simple as that.
