Excellent. That will save me some time preparing for my new build, thanks for sharing.

Hartman, I noticed that on your layout the OUT signal is going from the low filter 270K resistor (which is also connecting the low to the high filter). The OUT is shown by the light green wire and labled 5 on the attachment

On the Japanese schematic the OUT signal goes from between 820k and 100k. I am just wondering if this is as you built and what was the reasoning for this change. Everything else seems to match the japanese schematic

Also it looks like your first position for the low filter is at the 39K?

It's the same point, isn't it? Am I missing something?

Are you going for 1 deck or 2 decks? I Think Hartman went for 2 decks when he built his. Does it make any difference?
