Univox Micro Phaser clicking

[ohmelter]

Hello. I've recently built a Univox Micro Phaser per the Gotfired Divos schematic. Everything works, however I get this clicking sound when the effect is switched out....yes switched out. I wired it for true bypass. Why is there clicking bleeding through with clean signal when the effect is off?

Thanks

You might want to consider a number of things.
What true bypass scheme have you used?  3pdt or dpdt?  Perhaps your layout is causing the ticking to get in the audio path.

DPDT. What could cause signal to leak like that?
Do I put er up on a scope and try to find location of clicking?

Hmm.

- Maybe the wiring isn't as true bypass as you think. I've made a few wiring mistakes before.
- The usual suspects: stray capacitance in the wiring jumping the sudden change in the LFO circuit over into your nice, high impedance signal wires; and shared current running through ground wires.

A sure cure is to kill the LFO when the effect is bypassed. Maybe the Millenium C?

Hey R.G. Sounds like a plan. I'll try that today.
