Hi Charlie,
That's a great layout. I like the creativity and innovation particularly the TT and RH. I appreciate your time and effort in explaining how you built the project. You've inspired me to try my hand at building my own. I'm trying to figure out the wiring for the TT. Did you run a common wire with individual wires to each track? Is there a schematic you could post?
Also, I'm wondering how real TTs were powered.
Regards,
Casco
