I just put together my pair of EQN's.. One of them works fine and just needs to be calibrated. However, I'm having a problem with the 2nd one. The low freq switch doesn't have any effect on audio whatsoever. I've double checked the switch and looked for cold solder joints. I tested it with a meter to make sure the switch itself was working and I also swapped amp PCBs. Nothing made a difference! All other switches work fine.. Does anyone have a clue what my issue could be or other ideas on what i can check?

Thanks!

A good night sleep did the trick. Turned out that it was the jumper jrowell suggested to fix the LF response issue. Unsoldered the jumper and my LF switch worked. Re-soldered the jumper and all is still good! Although it looked fine to the naked eye, it clearly wasn't! ;)

On the droop fix, I understand that a wire needs to be connected in the green position.  What is the red wire on the photo ?  Is that something to ignore, or does a trace need cutting ?

The fix is to just jumper the green wire in the JRowell's photo a ways back. This is what I did and mine have been working great for a while.

Hello Peter,
saw in your website that you are out of stock for EQN parcial Kits.

Would you make a new run if I run a Feelers list and have more than 30 orders in the list?

Thanks

Anyone know the part number for the 1MM pin sockets ? I'm missing 10 and need to order.

I tried some from CAPI but they are too large dia. to fit in the PCB.

Looks like i might a Harwin ? and not mil-max

Edit* - Thanks Peter

I have a problem with one of my eqs. It works fine for about 4 or 5 hours then starts acting up. It starts to hum,  sometimes it starts as a slow pulsing hum and then becomes a constant hum.

Powering down for 15 mins seems to clear the problem and it will run clean for another 4/5 hours.

Ideas ? I going to start swapping opamps, DC/DC convertors and see if i can narrow it down

EDIT. I was the DC/DC convertor. Replaced it and all seems good

Can you enlarge a little bit the holes in the PCB to make them fit?

I use a small drill tool to enlarge the holes in PCB's, Works great.

The website for lazpro has gone down and I was just about to finish 4 eqn's . Would anyone have a schematic or something similar (build notes/ calibration guide / Bom) to help me finish?
Thanks
