the powerconnector.lbr was one i made, I'll upload it this afternoon (might have to boot up in windows)
I'll also look at the boards then

 

OK, don't forget that I need the datasheet for those connectors, or at least a part number and hopefully the manufacturer name.

 

the power connectors for the power supply?
those aren't a real part or anything, I was just using the larger holes to feed the wire through as a stress relief

"I SEE" said the blind man.... OTOH, for that connector, you show in the schematic +12V connected to the + terminal of it, but there are no entries on Tdocu/Bdocu as to which via gets which polarity connection. That should be painfully obvious by how the ground planes connect to the negative via, but you have to realize that you are planning on making this a kit. How many E-mails do you wish to have to answer because you didn't document on the board itself what those vias are supposed to be?

We've already had several exchanges just in this thread. Multiply that by however many kits you manage to sell.

 

OK, here's the next iteration. See the attached.

Board size is now down to 3.4" x 2.15". There are currently no provisions for mounting; ie: holes. TP1 and TP2 are in a position that's really not terribly useful at the moment. I'm thinking that more like 10% to 20% of full voltage would be a lot more useful. That means adding one more resistor per side, but it will make adjusting the supply voltage easier and more safe.

C9 and C12 (2.2uF) were deleted. C1 and C2 (100uF polarized) added. They can be rated for 16v. Try to select a cap that is low ESR and rated for 105°; these will be feeding L1 and L2. Ripple current will be up to ~1.6A.

 

OK, got that resolved.

Broke up the 220k resistors into 180k and 39k. You wind up with roughly 40k on the bottom, 180k on the top, so if you adjust the pots so that the test points are 33v, you're right about at 180v.

It would be a good idea to use 1% metal film resistors for the 39k and 180k's - wouldn't be a bad idea for the 470 Ohm resistor either, but that one is not nearly as critical.

There's room to put mounting pads/holes in 3 of the corners; the upper right is pretty crowded.

Go ahead and finish it off.

 

wookie... you miracle worker...
