For Sale Alps Black Beauty pots

Things you have for sale.
Ground planes on both sides, connected at the various GND pads.
The input/output and 2-ch GND's are all connected. Any feedback welcome if there are more optimal approaches.

I would recommend that the ground planes NOT be electrically connected to the mounting holes.
Allow plenty of clearance space for the nut and the metal surface on the other side of the board,
so there is no chance of contact between them and the ground planes on both sides.
Otherwise, ground loops can be formed.
 
@rayma The mounting holes are not electrically connected (there is no pad there, just a hole in the PCB).
I increased the the clearance sufficiently and I think it should be good now.

I did one additional change though and that is to not connect the GND of both channels, in case the design requires that they be combined elsewhere. (IN/OUT is still connected though)

IN1/OUT1 are the 4-pin Molex KK connectors, for the input and output --
CH1_SIGNAL / CH1_GND / CH2_GND / CH2_SIGNAL
 
OshPark order took a while. I got them yesterday and fit was 95% but not perfect. I made adjustments and ordered a batch from PCBWay (Black PCB with HASL) which I expect to receive in the next week or so. Please PM me directly if you're interested.

PCB's will be $4/ea.
They will go in a bubble mailer so I estimate around $3-$4 for USPS First Class.

I will post pictures of an assembled unit once I receive them.
 
Got them, they look good to me. I'll try them in a circuit later today or tomorrow...
