Back by popular demand! Please note that it can take a few months to get everything. Supply chain issues have made it take longer. Some have wanted different parts for that reason but the popular opinion still remains on preferring the very nice quality ones originally included.

Here's how it is different in settling time from the original.
Here's a comparison between resonances.
The Weco 983ZD are preferred terminals, but not always available as individual sale. For this reason I'm going to include them in the price of PCB, so that I can meet min order requirements for them and save everyone the shipping.
Price: $14ea ($10 per filter board, $2 per Weco, 2 needed per board)
Shipping: $11 US, priority USPS box
$20 CAD
$22 General international padded envelope (prices may vary due to a crazy world)
If ordering over 4x boards there may be an additional $10, depending on destination.
Need 32 filter board commitments to order.

So over the years people have asked about the old version, made by someone else.
It's probably time for an updated one. This one is a bit different. You may notice it does not have following capacitors after the choke. I have tried both ways, and my preference is without the following X2 capacitors. Also the capacitors prior to the choke are not varied in size because overall capacitance is more important - and they won't randomly resonate with each other.
The other major change is the addition of bypass resistors for the chokes. These don't ruin the filtration, but they do a good job of quieting the chokes that can get excited by different combinations of things on the mains.

Here's a comparison between resonances.

*2oz copper PCB (1oz is standard)
*Weco 983ZD terminals, copper alloy and can accept 2 wires for daisy chain. These are also safer, particularly if you use solid core wire that otherwise likes to make cold solder joints you can't see.
*X2 rated capacitors for safety, 4x 0.47uf. They are alternated for CFC (capacitor field cancellation).
*Discharge resistor for X2 capacitors
Coilcraft Comoco choke w/fuse or Bourns 8120/8121-RC choke w/o fuse & 15/16A/20A() max sockets
*Fuse clips are beryllium copper 3AG & 5x20mm options
*120/230v operation (parts & pcb)
*Mounting holes are sized to work nicely with M3 screws and standoff kits
*Size: 2.25x4.25in

I won't close this right away because we all know nothing is basically going to happen days before xmas. (it doesn't really close anyways, just run out of the min order)
Perhaps it is of no consequence, but I notice that Poolball69 appears twice in the running list in post #1.
Thanks. It does matter because either I cap it or I have to get a fair bit more orders once it gets up there.Perhaps it is of no consequence, but I notice that Poolball69 appears twice in the running list in post #1.
