9000: On the very tip end of the tube where there are 2 small pins witch one does the single wire from the neck board connect to?

9500: what would make just the green tube go full raster then off then on then off, on ect, other tubes are fine, This unit had a complete tube assembly swapped in from another unit that was working perfect. and the old green tube worked fine was just burnt a bit.

Thanks in advance

That is the G2 wire. look here.




Now for the other tube, did you swap the whole tube assembly with neck board and all?
I ask this because if it a LUG tube a stock neck board isn't modified to have the G2 on pin 6 that a LUG requires.

here is what has to be done for a LUG tube





I bet the tube going on full bright then off is the spotkill circuit due to you possibly having an LUG with a stock neck board. do not shut off the tube when full bright, let the spot kill work then shut it off when the tube is dark, or pull the heater voltage connection P14 under or to the side of the blue tube located on the mother board.

here is the pin outs for typical 9 inch tubes:
I added notes for my thomas tube mods.

Yes it was a Lug on 9500
