After a few days of stressing my newly converted deflection board yesterday I went on full set up. Then I realized that most of the convergence and geometry controls have no effect 
I don't have:
-Vertical blanking
-Tilt
-H-bow
-V-lin
-Keystone (at all)
-Pin-cushion (at all)
I know that the deflection board makes the keystone, but I measured the keystone input signal with oscilloscope and it didn't change at all regardless of the actual keystone setting...
regarding the manual, I also can't measure anything on the test points (TP8001-6) of C-drive board, however static convergence working well.
The manual kindly suggest to measure x-y pin of the wave board, but how the hell to do this? it is totaly inaccessible :/
During the def board conversion I took out the tubes to add an air bubble in them, could it be that during the reassembling of the tubes some wires loosed on the main board?
