I made the modification on an NTSC console, model SCPH 1001. I added PAL crystal oscillator, 221 ohm resistor and rfc. On the back of the board I removed a component that connected the PAL signal to ground.

There is a mistake on this, the RF choke and resistor are the wrong way around on the "parts to install" picture for top of PU8, you want RF choke on the power pin and the resistor on the clock out.

Are you referring to the photo I posted?
I left the resistor and choke in the same position that Sony left in the European and American console.
So is it wrong?
Thanks.

If you have installed them as per the photos you posted, the install is correct - the component positions indicated in my original document are wrong.
