Famicom shielding

[Jaek_3]

Does anyone know a way to reduce noise on my unmodded Famicom? It can get annoying. T h a n k s

I read a thread on some website (may have been this one) where someone replaced the plastic casing on the NES RF adapter, making the quality better.

Edit: Found it. http://www.famicomworld.com/forum/index.php?topic=12321.0

Most of the noise often comes from low quality power supply. Try another one.
