Hi all,

My board does not have solder pads for the 10-turns windings. So, I'm keeping some length of the wires and solder them to the closest other pad. Would it be right if I solder the wires as marked in red on this photo:

Google Groups does not allow me to paste a photo so I linked to a shared drive:

The board does have pads, but for some reason there's soldermask on the pads. I recommend scraping the soldermask off and soldering to the pads as intended.

OK. I have done a bit of scraping. But its a bit hard to see.
The ones marked in black are ground? Right?

Yes those are ground.

Here is an X-Ray view of the board:
