Just got the delay lines, and installed them on the luma delay buffer amp. The delay likes are 100 ohm impedance, so I used a 24 Ohm resistor to the video source to make it 100 ohms. And the delay lines terminate with 100 ohms, then the video buffer line driver makes it 75 ohm impedance again.

and what this buffer/delay line board looks like (I mounted it on the back of the CM7000.

Inside the set now:
