modulaterator ticking problem

[rosettastoned]

 I have built MB modulaterator layout  with a zeropoint DD. and guess what I've got a ticking issue, at first I thought it was my pcb so I decided o etch a new one, but ticking came back once again.  I'd like to try the 1776 layout but can't find it.

some signs that could help, I can hear the tickin even when the MOD is off, I have worked on it during the evening and notice that  the IC generate the ticking, I changed it for a 4558 and the noise increased, now I set a TL062 but the sound is just lil bit low.

please help
