I built the noise section of the DR-55 drum machine. It is generating noise (white noise which is OK) along a hum sound which I don't understand where it comes from since I am using batteries (6v) . I am connecting the output to a set of computer speakers that are AC powered (could this be the source of the hum noise?). How do I get rid of the hum noise? Also can you please tell me what is a 22/10 capacitor ? I try various values in the circuit but none get rid of the hum noise.
Thanks
