i still need to double check this layout against the schematic when im fresh and not burnt out.
(wouldn't recommend building it just yet, unless you wanna check it yourself)
but once ive done that, ill be ordering the 1/2W resistors and fatties to make a start.
i can at least confirm that the 34-hole-wide board does indeed fit in a 1590BB2.
If you move the 15K and 22K resistors directly below the diagonal jumper (15K to the right one space and 22K to the left one space) and also swap the red and the green jumpers associated with them then you can move the cut at 16-I one space to the left and everything fits.
