I have had too much on my plate the last two months, but there is really no excuse!
I must admit that I did not pay enough attention as small shunt values like that are not common in the high-pass. None the less, my sincerest apologies for the big inconvenience! I have a nicely match pair of 0.47s in the mail post haste. If you do not already have tracking, you will soon.
On another note, the work is looking good. Did you happen to give attention to the direct in which you installed the caps?
Take a magnet to the back of those binding post. What all is magnetic if any?
