when i can hear it click it means it's working right?  ???

Yes, sounds like the relay is working. When you say the HF section doesn’t work do you mean no signal or the controls aren’t working?

Only the gain control in PEAK mode on one side, everything else works
and
Low mid gain control on both sides

Is it possible i used the wrong potentiometers? Mine only have 3 solder lugs instead of 4 printed on the pcb. But then i think it's strange that most of the pots work..
i used this BOM

You’re not using center tapped pots? I don’t know why it’s working. I would think it wouldn’t work.

Maybe you soldered pots into wrong holes?

It should be okay to use 3 lug pots since if you observe original board designed by mr. Porter it uses only 3 lugs. Fourth lug is not connected.
I've attached PCB Tracking.pdf here so look it up

yes i need CT pots. I just missed that fact, had the wrong BOM.
Thanks for pointing it out

I used the two 5K resistors twisted together trick to get my EQ going.  You could also rig up an On-Off-On toggle switch for max gain, min gain and no gain.

The gain control is a good candidate for a rotary switch for this reason.

I'll eventually think about upgrading but first i gotta make this work  ::)

Each section is kind of an island to its self. You only need to attach controls to the section you are testing. To be extra sure you could only load opamps into the section you are testing. When you are sure one section is working move onto the next.

Hey guys,

I'm thinking to build a NetEq. I heard some samples and seems to be a quite interesting eq. I found the pcbs on pcbgrinder.

I would like to know an average of how much I will spend to build a stereo version.

Is there a component list available?
Pcbgrinder sells the pcbs only.

Thanks!

It depends on which switches you use, it could be approx. 600-700€ if you use the cheaper ones (it also depend on the choice of case and components).

If you plan to use Elma’s, things get to start expensive...

I'm searching for a good/"working" gerber for this eq.

Files I have seems to be misaligned and not readable.

Thanks

How about keeping it simple and buy a board at https://www.pcbgrinder.com/produktside/neteq
