Can't see the PCB's in the store? I would say no.
On a side note, does anyone know the Input and Output impedance of this kit?

Input is 1/2 the value of whatever level pots you choose. Odinarily 50K ports,
so 25K
Output is 180 ohms.

If I wanted to drive long XLR interconnects into it can I use 100k pots to provide better impedance matching?
You can use what you like, but 100K doesn't improve the performance
with long interconnects, where the capacitance of the cable becomes
a factor with respect to the output impedance of the source.
The capacitance of the Jfets is about 30 pF, which gives an input rolloff
frequency of about 300 KHz for the halfway position of a 100K pot.
It's not a real problem either way.

At last count we were considering both sets of holes.
The small holes for wires are good for 24G and the larger ones for
pcb rca connectors will work with 16-18G without complaint.

I am doing a final rework on the board, as I figured out a clever way to increase
the range of some of the filter settings without more parts.
This will be done maybe today, and I will see prototypes in a week or so. A week
after that I will have checked it, and then orders for parts can proceed.
I don't think it will be available before the end of the month. More like August.

When the kit comes out, full schematics will accompany it,
and you can do your own as you like.
As it is, the schematic is still in flux....

Finished and test boards here in the lab. I am working on the documentation,
and have informed the store of its pending availability.

Papa: If you need someone to build one, Im ready. Let me know. I can send gifts to Colorado too..
