AionFX Redshift Phaser Issue - Help Needed

[mickey.bellinello]

Hi to all!

I just built a redshift phaser. It works but to me there is a problem with the feedback knob.

When i turn it clockwise, after 50%, i got a big volume drop and it seems very strange.

Here's the kit instruction:

Any ideas? What can i check??? I have no voltage reference unfortunely.

Thanks

Except if obligatory controll of tracks and points of soldering, from tin dirt and undsired bridges, controll C11 if not damaged, and R24-26. Especially R25 and 26. At first. And if feedback setting is low, everything works ok?

And if feedback setting is low, everything works ok?

Exactly, if the feedback is before 50% I have full volume. If I crank it the volume goes down...

It seems pretty strange.... I checked the pot and it works properly...

If volume and phasing effect is ok, controll those three parts I assigned. Here will be something wrong. I suppose, that Feedback Pot is not "short-connected" with ground anyway.

Hi to all, rececked all and all seems ok.

I asked in various forum and it seems that is "normal operation".

Seems a bit strange but it is.

Thanks for the help!

Another question, I added a rate pulse led using this method:

9V -> LED -> 2N5087 emitter,
2N5087 base to Q4 Emitter
2N5087 Collector to 47k R to ground.

Not super smooth but it pulse.

Any ideas to smooth it out a bit?

Thanks
