I beleive this could be usefull for many americans, because I know that they don't have easly an RGB input on their TV.
ok firstly I explain what happen to me.
I just received my 1st PCB 2 days ago (Ketsui) I already created my own cabinet using a simple TV with an rgb scart input. it was working fine with consoles.
Then I created a Jamma to Scart adapter then plugged my new PCB and ... Horror all the colors was too white
I measured the voltage and the output of an arcade are around 5Vpp and my tv accept somthing like 2Vpp for the RGB signal.
I tried the PCB on my trusty commodore 1084 monitor, and all was fine.
after some research on the web I discovered a guy who sale arcade monitor's mother board and explain what you need to do te repair your screen.
I thought well if it's that simple why not mix the motherboard of my commodore monitor to my 21inch TV tube.
1st I cheked if the connector behind the tube was both the same number of pin, and yes both was 10pins.
then before I transplant the things I measured the impedance of the vertical and horizontol coil of my TV and my monitor. all matched it was both low impedance
I took of the cables connectors from my TV and replaced them by the commodore connectors. pluged each connectors carrefuly.
turn on the things, and the picture was all white
I find 2 potentiometers behind the tv tube, on the newly arcade little board,
one is for the sharpness, and one for the brightness, turn it down and... voila !!
my cabinet have now a real arcade monitor in it, I can change all the parameters of the picture as I wish with all the potentiometer of the commodore monitor
So if you like DIY and now elelcricity, you have an old TV (even broked you only need the tube), a commodore monitor, then you are ready for your new arcade monitor :p
if you dont have a commodore monitor, you can buy for less than 100$ a new arcade monitor mother board here:

I hope it could be helpfull to someone.
