--- End quote ---

I would say they are 120nF (0.12uF) 400V 5% caps.
2takt:
ok meter says 11.5ohm good if<10uf so they are good too

i got two that the meter cant measure, the green one(cant read the value) and a yellow one 4n7j100. the rest seam ok to me.

i think i will do a testrun today or tommorrow, i got the ice spray but its flammable i dont know if thats a good idea on the back of my tv?
this north south module is a correction for the planar? tube. isit possible to bypass this module and hock my yoke directly in the mainboard without destroying something?
Benta:
It seems you're a bit in over your head here.
Like I said, start with the high voltage section, odds are your problems are there. Resolder everything.
N/S and E/W correction are secondary, don't start fiddling with that until the basic functionality is right, which is making certain that your horizontal deflection, high voltage generation and auxiliary voltage generation works 100%. This is all in one 15625 Hz transformer/circuit, by the way.

Pay special attention to the safety capacitors across the primary of the horizontal transformer. These need to be soldered 100% reliably.

Cheers.
2takt:
first time working on a crt:)
ok i will do that.

can you tell me where this cap is?
2takt:
look something was hidding under the plastic :)) i could spot 2 more but this was the worst of them
