Ok, thanks Don.

I feel kind of guilty because seems like I should have a bunch more questions. But I'm just not having that much trouble so far. even grounding the crystal cans went pretty smoothly hi hi once I read all the suggestions on how to do it (tin the cans first! Then hold the ground leads in place by putting a spare anti-static pad leftover from the IC's under the board and sticking them into it through the grounding holes).

As for tinning the toroid leads, I did find that the solder blob method was ineffective. Perhaps a 700F tip just doesn't get hot enough to melt the insulation? Instead, I'm sanding the leads first with a bit of sandpaper to get the stuff mostly off then tinning. This gives a very nice tin on the wires and good solder connection on the board.....

Is this meant to be done with an 800F or hotter tip?

Thanks es 73,
