Re: Apple Lisa CRT replacement?

Use the deflection yoke from the Lisa.

Did you get a horizontal or vertical line? Did it seem to be the entire picture, just squashed down to 1mm? Nothing on the CRT socket could cause a loss of vertical or horizontal deflection.

PS: Just about any 12" B&W CRT will fit. Here's a (real time) video I made of swapping the burnt in CRT on my 2/5:
