In this instance just the type of SRAM drastically changed the result.

But how would the notch filter distinguish between the parasitic signal and graphics that produce the frequency ?
Sorry, I only saw the initial screenshot in the thread, not the subsequent tweets. That said: The jailbars seem to be about 1 cycle per tile. That's far lower than any signal that'd be getting thrown around the Famicom's internal buses. Tuned properly, it could work.

I was thinking more along the lines of something that could be connected in-line with the Famicom's video output in order to mute the jailbar effect. Given the NTSC color burst frequency, notching out a frequency of 1 cycle per tile shouldn't affect the eventual output.

From what I can tell, the SRAM seems to be parasitically pulling a couple milliamps off of the the bus, which leads to cycles of voltage dropping (increased luma) across the raster, one per nametable square at the beginning - corresponding with nametable CIRAM fetch by the PPU.
