Pork Barrel clock noise

[jonnygreentrees]

Mentioned this in my build report but thought it was worth mentioning here too.

Just finished my Pork Barrel and I'm getting a quiet ticking that is audible even when the pedal is bypassed. The ticking changes speed with the rate knob. It was much louder until I wiggled the bottom right transistor and then in got quieter but it's still there

Any ideas?

First thing I'd try is shortening your off board wiring, can you plug the effect in and move all the wiring clear from the board, see if it reduces in volume.

Thanks I'll give that a go

Balls it is the wiring, when i move the PCB out the case the ticking goes away. Guess I'll have to rebox in a 1590BB

No need for that. Start by moving the wires around like sturgeo mentioned. You might find spot where it doesn't tic at all. Try moving them as far as possible from clock (IC3). If that doesn't help then you can try shielded wires for input and output (the shield connected to ground on one end, nowhere on the other).

Already tried that and unfortunately there was no such spot.

I'll try shielded wires for input and output is that board I/O to switch or switch to I/O jacks or both?

Cheers

In terms of shielded wire would this do the job?
