I'm not sure but I think adding jumpers might just worsen the jailbars.

If you lift pin 21 you sacrifice RF as Famicom_87 said. It has been done for years to reduce the noise but the AV-mod research has not stood still since then. I've explained my understanding of the current AV-mod situation here. Source is also there.

I can really recommend the AN8009 multimeter. It's cheap and does an amazing job.

Thanks for the advice I'm going to buy a better multimeter as mine really is missing the continuity test and il get back with the results in a few days time

Related Question: How much would gauge of the jumper wires to the CPU and PPU matter for this mod? xIcMans mod has me thinking about modeling a pcb holder that clamps to each side and hangs under the existing PCB. I would either drill small holes in the console5 pcb or just run jumpers over the side to the PPU and CPU leads on the bottom of the Famicom pcb. I would use a heavier gauge for the 5v and ground.

Well, easy enough for me to try it without lifting. Hopefully some results this week if I can get some time set aside.

So just attach the lead to the leg in place?
